The TBL-8200 series is a two-component, addition-type liquid silicone rubber. It offers excellent high and low temperature resistance, superior weather resistance, good tear strength, tensile strength, resilience, and yellowing resistance. It is FDA, LFGB, ROHS, and REACH certified.

Features:

• High strength

• Fast vulcanization

• Excellent yellowing resistance

• Liquid injection molding

Typical applications

• Conventional silicone rubber products

Instructions

• It is recommended that users use a liquid injection molding machine to inject the mixture into the mold to produce the product.

• Components A and B must be thoroughly mixed in a 1:1 weight or volume ratio. The curing time is determined by the mold temperature.

Higher temperatures shorten the curing time, while thicker and larger products require longer curing times. The mold can be disassembled after curing.

• If the machine is shut down for an extended period (more than two days), either Glue A or Glue B can be injected into the mixing section separately. Alternatively, the remaining Glue can be cleaned out.

Precautions

• Avoid contact with condensation-type silicone rubber vulcanizers during operation. Other possible causes of non-vulcanization of the compound include amines, sulfur- and phosphorus-containing compounds, and some metal salts.

• Component A of this series of products contains a catalyst, and Component B contains a crosslinker. When switching between products from different manufacturers, conduct tests to avoid crosslinking reactions.

Packaging Specifications

This series of products is packaged in 20kg plastic drums or 200kg iron drums lined with plastic bags.

Storage and Transportation

• Store in a sealed container in a cool, dark place, away from rain and direct sunlight.

• This series of products is non-hazardous and has a shelf life of one year. They can still be used after passing re-inspection.

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.
