Product Features
▪ Good mechanical properties ,UL-94-V0 recognized
▪ Good processability
Typical Application
• Flame retardant type products
How To Use
1. Suggest that the consumer use the liquid injection molding machine to inject into the mold and manufacture products.
2. The two components of A and B must be completely mixed according to the weight or volume ratio of 1:1. The vulcanization time is determined by the molding temperature. At high temperature conditions, a short time is required for product forming. If the silicone product is thick and large, it takes longer time to mold. After vulcanization, the mold can be disassembled.
3. If the machine is shut down for a long time (more than two days), either inject component A or component B into the mixing section alone. Or clean up the remaining rubber.
Caution
1. Avoid contact with condensation-type silicone rubber vulcanizers during operation. Other possible causes of non-vulcanization of the rubber include amines, sulfur- and phosphorus-containing compounds, and some metal salts.
2. In this series, component A contains catalyst and component B contains cross-linking agent. When products from different manufacturers are used, tests shall be carried out to avoid cross-linking reaction.
Packaging
This series of product is packed in 20 kg/plastic straight pail or 200 kg/metal drum, with plastic liners.
Storage and Transportation
1. Products should be stored in sealed condition, kept it in a cool place and avoid rain and sun exposure.
2. This series of products are non-dangerous goods. The valid period is 1 year. If the products exceed the storage life, it can be re-tested to prove the curing speed is acceptable, if so, it can be used.

Remark: The physical and mechanical properties of the 2mm test piece were prepared under the conditions of 130℃×5min, and the curing time test conditions were 120℃×5min. The above data are typical data.
Transparent liquid silicone rubber is a high-grade, hard-wearing, non-toxic liquid polymer having an astounding range of uses in a wide variety of industries. It is also a versatile material that can be used in a wide range of other industries too, but is primarily used for its high mechanical strength and resistance to a wide range of chemicals as well as heat and weathering. As it has no crystalline structure, it is thermally broken into two crystal sheets upon heating and hence can be used as an alternative to hard plastic. The high degree of tensile strength combined with flexibility makes it a particularly good choice for high-alloy structural parts such as engines, pipes, landing gears, and so forth.
Like all materials used in the manufacture of plastics, liquid silicone rubber exhibits the common properties of thermoplastic, ie: (I) it is both rigid and elastic; (ii) it is highly resistant to both mechanical and chemical stress; (iii) it is a homogenous material, that is, it will not yield to any cross-formation due to heat during manufacturing or after manufacturing; (iv) it is widely used in the creation of a wide range of parts requiring great tensile strength and high wear resistance; (v) it exhibits quite a high degree of directional control during forming; (vi) it does not become brittle when exposed to changes in temperature and (vii) it has an extremely high correlation with the specific gravity of the curing melt. This last property renders it useful as a control surface for curing in a thermosetting manner.
Transparent liquid silicone rubber tends to exhibit a very high degree of conformability, that is, it can be formed into the perfect thin-film suspension by using a simple roll process. This ability to form thin-films results in greater design flexibility and reduced waste. In addition, silicone oil tends to exhibit excellent mechanical properties, which includes extreme tensile strength, homogenous flow, excellent electrical conductivity, excellent thermal conductivity, the ability to prevent solvation, and the ability to prevent swelling after forming. It also exhibits excellent resistance to erosion, crushing, and abrasion. Silicone oil's other unique physical characteristics include:
In general, transparent liquid silicone rubber has good insulating properties. The liquid form shows relatively low resistivity to vibration, heat, and cold. The honeycomb design of liquid and semi-solid states allows them to exhibit high electrical and mechanical properties. Clear, semi-diametric, and tensile silicone rubber are suitable for manufacturing many different types of molded products, including pumps, hoses, seals, pumps, and many others.
