Silicone rubber characteristics and application/selection of raw rubber

　　Organic silicone rubber is a special synthetic elastomer formed by linear polysiloxane mixed with reinforcing filler and vulcanized under heating and pressure. It perfectly balances mechanical and chemical properties to meet the requirements of many demanding applications.

　　Silicone rubber excels in the following areas:

　　High and low temperature stability

　　Inert (tasteless and odorless)

　　Transparent and easy to paint

　　Wide hardness range, 10-80 shore hardness

　　Chemical resistance

　　Good sealing performance

　　Electrical property

　　Resistance to compression deformation

　　In addition to the above excellent properties, silicone rubber accessories are particularly easy to process and manufacture compared to conventional organic elastomers. Silicone rubber is easy to flow, so it can be molded, calendered, and extruded with low energy consumption. Easy processing also means high production efficiency.

　　Silicone rubber components can be supplied in the following forms:

　　Compound: This ready-to-use material can be colored and catalyzed depending on your processing equipment and use. Base material: This type of silicone polymer also contains reinforcing fillers. The rubber base can be further mixed with pigments and additives to form a compound that meets your color and other manufacturing requirements.

　　Liquid silicone rubber (LSR) : This two-component liquid rubber system can be pumped into the appropriate injection molding equipment and then heat-cured into molded rubber parts.

　　Fluorosilicone rubber compounds and base materials: Fluorosilicone rubber maintains many of the key properties of silicone, in addition, it has superior chemical, fuel and oil resistance.

　　Choice of raw glue

　　Selection of raw rubber: Select raw rubber with different characteristics according to the performance of the product and the conditions of use. Vinyl silicone rubber: products require the use of temperature in the range of -70 ~ 250 ° C, vinyl silicone rubber can be used. Low benzene silicone rubber: When the product requires a high temperature of -90 ~ 300 ° C, low benzene silicone rubber can be used. Fluorine silica gel: When products require high and low temperature resistance and fuel and solvent resistance, fluorine silica gel is used
