How LSR Liquid silicone rubber can reduce production times for the wearable medical technology market.
As the wearable medical technology market is growing, liquid silicone rubber (LSR) material science is rapidly advancing with it. The industry shift toward wearable health devices and externally communicating medical tools has led to higher growth in both traditional rubber applications and newer ones. The unique properties of LSR – and other silicone materials – have played an important role to reduce time, cost and approval processes for development of new medical devices and drugs for decades because of their safe long proven history in the market
Accepted for a variety of medical uses since the early 1950s, silicone materials have two properties that are critical for driving industry innovation: biocompatibility and biodurability. Silicone elastomers are the material of choice for long-term medical implants since they can last for more than 30 years – far longer than any other material. Because silicones are inert, they are biocompatible with the human body, with no adverse effects on human health.
Extensively studied and approved by the US. Food and Drug Administration (FDA), the proven biocompatibility of silicone materials simplifies new drug and device approvals. They also offer a range of unique properties that no other class of polymer offers. For instance, LSRs offer properties not obtainable with organic rubber materials, especially heat resistance, extreme low-temperature flexibility, biological inertness, and an intrinsic capacity for.
Recent advances in chemical formulations which improve injection molding processability of LSRs for the ongoing replacement of traditional materials in respiratory, external communicating and wearable monitoring devices, among others. Ideal for intricate designs and close-tolerance parts, LSRs are pumpable thermosetting silicone elastomers that can be processed by molding equipment.
In fact, LSR product development has resulted in the improved processing parameters to provide the greatest value and ease of use. The handling of LSR materials during injection molding is an inherently clean production process since the component chemicals are sealed within a closed system. Ambient air contacts the cured parts when they are removed from the mold, which limits exposure to the manufacturing environment. This also improves part quality, because contaminants can diminish physical properties of the cured rubber.
Liquid silicone rubbers are two-part, platinum-catalyzed elastomers with an operating temperature range between -40°C to 200°C, with short peaks up to 260°C. With post cure, LSR offer a very low compression set and has improved durability over organic rubbers. These polymers are translucent, and can be pigmented to match many color requirements. New LSR formulations can cure at lower temperatures and have quick cycle times, which translates into quicker processing and greater throughput.

Liquid silicone rubber has excellent tear resistance, resilience, yellowing resistance, thermal stability, heat resistance and aging resistance. Mainly used for baby products, medical products and electronic products (keys).
Typical liquid silicone rubber is soft, elastic, non-toxic, odorless, transparent, and medically safe, that is, food safety is extremely high. If it needs to be applied in food grade or medicine, some certifications of silicone are essential.
Liquid silicone rubber can be divided into addition/Platinum cure silicone and tin cure silicone.
Addition/Platinum cure liquid silicone rubber belongs to food grade, food-grade liquid silicone is non-toxic, odorless and molded silicone, also known as FDA silicone or environmentally friendly silicone. It has the characteristics of high temperature resistance, high pressure resistance, and flame resistance. It is often used to make food molds, chocolates, cakes, and directly made into pacifiers and sealing strips. And other silicone products.
The following is a brief introduction, what are necessary certification for food-grade liquid silicone rubber raw materials?
The certification reports for food grade liquid silicone rubber raw materials are (ROHS, halogen, PAHS, REACH, FDA, LFGB, MSDS, USP, NSF, UL yellow card, etc.). At present, the more authoritative certification agencies include SGS, TUV, CE and other institutions, and there are CTI and other institutions in China.
1. The ROHS report is an environmental report, which mainly detects six heavy metals: lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr(VI)), polybrominated biphenyls (PBBs), polybrominated diphenyl ethers ( PBDEs).
2. Halogen detection includes (fluorine (F), chlorine (CI), bromine (Br), and iodine (I).
3. REACH is different from the RoHS directive, and the scope of REACH is much wider. Now it has increased to 168 tests, which is the abbreviation of the EU regulation "REGULATION concerning the Registration, Evaluation, Authorization and Restriction of Chemicals" (REGULATION concerning the Registration, Evaluation, Authorization and Restriction of Chemicals). It was established by the European Union and was established on June 1, 2007. The chemical supervision system implemented from Japan.
4. The tests done by FDA/LFGB for non-food drugs are mainly food contact materials. FDA is the food certification report of the United States, LFGB is the EU food certification report, and FDA/LFGB are two completely different standard.
6. The MSDS report refers to the chemical safety specification, also known as the material safety factor table, the chemical safety technical specification and the chemical safety data specification.
7. UL yellow card refers to the flame retardant grade:
- Passed UL certification: (flame retardant level)

Your best reliable liquid silicone rubber raw materials supplier in the world!
Foshan Tian Bao Li Silicon Engineering Technology Co., Ltd, as one of professional liquid silicone rubber manufacturers, Here, let’s tell you more about Liquid silicone rubber.
1. About Liquid silicone rubber
About Liquid silicone, also called liquid silicone rubber, is a broadly-used silicon polymer which is composed of silicon, carbon, hydrogen as well as oxygen at the elemental level. At the molecular level, this silicon polymer comprises a silica and oxygen backbone, different from the vast majority of polymers which are made of the carbon backbone. Liquid silicone rubber, if more specifically categorized, can be regarded as an elastomer.
When it comes to how this material was found out and used, in fact, it’s developed from the solid silicone. Solid silicone-based elastomer was first used in the 1940s by chemists due to its heat-resistant characteristic. Then it takes the dominant position for electric motors and generators insulation as the electrical insulator.
Gradually, with the advance of separating technology, the precipitated liquid silicone rubber is separated into a two-part platinum-cured elastomer which is what is called the liquid silicone. Unlike solid silicone which is solid, the liquid silicone rubber is in a liquid state and has high fluidity, making it the perfect material choice for injection molding.
Liquid Silicone Rubber (LSR) is a two-component system, where long polysiloxane chains are reinforced with specially treated silica. Component A contains a platinum catalyst and Component B
The primary differentiator between liquid silicone rubber (LSR) and high temperature silicone rubber (HTV) is the “flowable” or “liquid” nature of LSR materials. While HTV can use either a peroxide or a platinum curing process, LSR liquid silicone rubber uses only additive curing with platinum. Due to the thermosetting nature of the material, liquid silicone rubber injection molding requires special treatment, such as intensive distributive mixing, while maintaining the material at a low temperature before it is pushed into the heated cavity and vulcanized.
In addition, Liquid Silicone Rubber has become a common material used to over-mold onto other parts manufactured from a variety of plastics.
Manufacturing process steps for Liquid silicone rubber:
A: Meter-mixing delivers the two-part mixture at a 1:1 ratio, into a static mixer, within an accuracy of ±1%. The precision of the material allocation prevents off tolerance products and reduces material waste. The closed meter-mix system also keeps the product clean because the mixer seals the mix from dust and moisture. The system also allows for the controlled addition of pigments and other additives.
B: The second stage of the liquid silicone rubber injection process requires the use of highly automated and modified LSR injection molding machines. Once operable, the machines require very little labor. The greatest capital expense incurred in the liquid silicone rubber injection molding process involves the cost of the mold design and fabrication.

In recent years, baking pans, cupcake liners, spatulas, and other kitchen tools made from silicone rubber have become much more common. They are cheap, non-stick, pliable, and come in bright colors.
Food storage is one of the more long-standing applications of silicone rubber. Not only are they safe for food contact and don’t react chemically, but they also do a good job of maintaining the temperature of its contents.
Liquid Silicone Rubber is recognized as a hypoallergenic material. It is used widely as a container or delivery system for skincare or cosmetic products. Most makeup and lipstick are packaged using silicone rubber as it remains inert even when in contact with the product during long-term storage.
Liquid Silicone Rubber is one of the more environment-friendly alternatives to natural animal hairs as material for makeup brushes. They are a little softer than nylon but are similarly cheap and gentle on the skin.
Liquid Silicone Rubber is applied in many coating applications.
This is because liquid soft silicone rubber has good adhesion to textiles and glass fabrics.
Liquid Silicone Rubber as a coating material brings the unique properties to airbag fabrics. LSR Liquid Silicone Rubber coated fabrics have thermal resistance, flame resistance, high tear strength and good adhesive properties.
There are many seals used for automotive. Just a few examples are connector seals, wire seals, and O-rings. Automotive parts are going to become smaller and lighter. These Liquid Silicone Rubber coated textiles and fabrics have non-slip and excellent mechanical properties.
Liquid silicone rubber is non-conductive because of its chemical nature. It is a good electrical insulator and has powerful hydrophobicity. In addition, Liquid Silicone Rubber is easy to make and handle, and is lighter than porcelain.
Chemically Resistant and Inert
Another property of the medical grade liquid silicone rubber which makes it the favorite material of choice for various applications over other manufacturing materials is its chemical resistance. Liquid silicone rubber made of the silicon-based backbone is an inert chemical material, which makes it hypoallergenic and not reacts with other chemicals.
This makes it the primary material of choice for applications that require to be exposed to oils, solvents, acids, and bases. Besides, the chemical resistance also means that liquid silicone is biocompatible and non-toxic, making it safe for items that need to keep contact with food and medical devices.
Health Care field
Liquid silicone rubber demand will increase with the increase in demand for home health equipment and disposable equipment. For example, the aging population in the United States will increase the demand for urinary devices and personal diagnostic equipment such as catheters. Liquid silicone rubber hygiene, hypoallergenic and easy to clean, disinfected characteristics are favorable for outpatient medical and health facilities.
Liquid silicone rubber as a polycarbonate positive positive pressure ventilation mask on the sealing part of the more and more used in the treatment of sleep apnea disease, this material is good sealing effect, used in the skin is also comfortable, easy to clean and Disinfect and inhibit bacterial growth. The biocompatibility of liquid silicone rubber makes it no allergic reaction with skin tissue. Finished products can also be designed to be transparent, so that caregivers can determine whether they are anxious or uncomfortable by observing the user's expression.
At the same time, clear liquid silicone rubber in the development of needleless syringes play an increasingly important role, it can help reduce the amount of treatment during the needle. For example, a polycarbonate-coated liquid silicone rubber check valve mounted in an intravenous injection tube can release the drug directly without the use of a hypodermic needle while avoiding contamination.
3. Why to Choose Liquid Silicone Rubber
Due to the chemical structure of including hydrophobic, water-fearing, and methyl groups, liquid silicone is also water-resistant. This characteristic makes it an excellent option for products that are electrical or are linked with electricity.
In short, liquid silicone rubber is a special material that ticks all the boxes of the properties that a powerful material should own. Due to the properties of flexibility, stability, translucency, thermal conductivity, non-conductive electricity as well as fast-curing capacity, liquid silicone is a valuable material versatile for various industries and applications.
Low Manufacturing Cost
As mentioned earlier, liquid silicone rubber lends itself well to the very fast curing processes, leading to ultra-fast manufacturing with large-scale and automated processes. Also, the manufacturing process is very simple and easy.
LSR liquid silicone rubber Advantages:
Automated process, fast cure cycles–excellent productivity, multi-cavity molds, extremely low flash tolerances, high strength products, low viscosity = low injection pressures. Overmold and two shot capabilities, make Liquid Silicone Rubber one of the fastest growing Technologies in the industry.
One of the more valuable characteristics of liquid silicone rubber is that it lends itself well to rapid manufacturing processes. Upon combination of its components, the uncured gel-like polymer can be injection molded. This allows for large-batch processing, ensures repeatability, and can be adapted to automated processes. The suitability of liquid silicone rubber to fast-paced manufacturing is one of the main drivers of its commercial value.
4. Easy to pack, storage and ship your Liquid silicone rubber
Liquid Silicone Rubber may be packed in bulk 200kgs Iron drum or 20kgs plastic drums. It’s not necessary to add bubble wrap, foam or air cushioning products to your packaging. Those are necessary for some other types of materials. In fact, the costs may be factored into your piece price, can spur extra handling charges, and may cost more for the freight charges due to the extra weight added to your package.
Liquid Silicone Rubber products are easily stored and lower the storage concerns many companies face. Silicone components alone, without added features such as adhesive layers, 1year shelf life and may be stored shipping-boxes-storage indefinitely. They may be left in the original shipping drums, allowing them to be stacked in a warehouse. If you need your product readily available for use, they may be exposed during storage and can be quickly and easily cleaned from dust which will not harm them. Silicone products also can withstand temperature changes which may affect many storage areas.
If the package falls during transportation, receiving, storage or retrieval, there is no need to worry about your product, it will not affect production.
Recommended Storage Conditions
It states “The relative humidity shall be such that given the variations of temperature in storage, condensation does not occur. In any event, if the elastomers are not stored in sealed moisture proof bags, the relative humidity of the atmosphere in storage shall be less than 75%.” The last of the main three for storage is light. Silicone rubber should be stored away from direct light. This includes direct sunlight, and even intense artificial lighting. This means that the optimal storage for Silicone rubber products will be in a moisture proof sealed bag, stored in an optimal temperature environment kept away from direct light sources.
