Characteristics and application of silicone rubber

Silicone rubber is a special synthetic elastomer, which is made of linear polysiloxane mixed with reinforcing filler and vulcanized under heating and pressure. It perfectly balances mechanical and chemical properties, thus meeting many of today's demanding applications.

Silicone rubber excels in the following areas:

High and low temperature stability

Inert (tasteless and odorless)

Transparent, easy to color

Wide range of hardness, 10-80 shore hardness

Chemical resistance

Good sealing performance

Electrical properties

Compression resistance

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

Silicone rubber miscellaneous parts can be provided in the following forms:

Compound: this ready to use material can be colored and catalysed according to your processing equipment and end use. Base material: this kind of silicone polymer also contains reinforcing filler. The rubber base material can be further mixed with pigments and additives to form a compound to meet 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 thermally cured into molded rubber parts.

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

Selection of raw rubber: raw rubber with different characteristics shall be selected according to product performance and service conditions.

Vinyl silicone rubber: products required to use temperature in - 70 ~ 250 ℃ range, can use vinyl silicone rubber.

Low benzene silicone rubber: products require the use of very high temperature range - 90 ~ 300 ℃, low benzene silicone rubber can be used.

Fluorosilicone: when the products are required to be resistant to high and low temperature and fuel and solvent, fluorosilica gel is used
