Silicone rubber (VMQ)

Silicone rubber is a saturated non-polar rubber obtained from quartz and injected with methyl, vinyl and other side chains by silicon atoms. The addition of different side chains gives silicone rubber different properties. Silicone rubber has excellent heat resistance, ozone resistance and oxidation resistance, and its electrolyte stability is very good. It also has the characteristics of resistance to lubricating oil, chemicals and solvents. Among all elastomers, silicone has the best elasticity at low temperatures. However, silicone also has some disadvantages, such as low tensile strength and weak wear resistance, and is generally not used for dynamic sealing.

Temperature range

-60℃ to +225℃, special silicone rubber can reach high temperature of +300℃, low temperature of -100℃ (TR10 can be at -100℃)

Hardness range

Shaw A25 degrees to 90 degrees

Color

Black, brown, green, white, reddish brown, yellow, blue, red, orange, transparent, gray, or as specified by the customer

Application

Rubber performs well in extreme environments and temperatures and is commonly used in the automotive and aviation industries. It also has excellent electrical insulation properties and can be used in environments with strict performance standards.

In addition, silicone rubber can be tasteless, odorless, and non-toxic, so it is also a good material for home appliances and the food industry:

For contact with food or beverages, silicone rubber can be formulated using "white list" ingredients specified in FDA 21.CFR 177.2600.

For drinking water applications, silicone rubber can apply for approval from the National Sanitation Foundation (NSF).

Silicone rubber is commonly used in automotive systems, such as car trunks, oil filter valves, lighting gaskets, etc.

Silicone rubber parts can be used in medical systems that specifically need to comply with USP CLASS VI
