Silicone O-Rings

Silicone Rubber (Q, MQ, VMQ, PVMQ)

Physically, silicones are based on silicon, an element derived from quartz. To create this class of synthetic elastomers, pendant organic groups such as methyl, phenyl and vinyl are attached to silicon atoms. The different additions of side chains can achieve significant variations in properties. Silicones have excellent heat, ozone and corona resistance, are very well dielectric stability, and resistant to many oils, chemicals, and solvents. Silicones possess the best flexible property at low temperatures, but it also has some weakness like low tensile strength, poor tear strength and wear resistance.

Service Temperature

For Silicones the service temperatures are from -60 C to 225 C. Some special types can be used in extreme temperature up to 300 C and down to -100 C.

Hardness

25 to 90 Shore A are available.

Color

Black, brown, green, white, rust, yellow, blue, red, orange, transparent and gray are available, or any assigned color from customers.

Application

Silicone rubber performs well under environmental and temperature extremes. It is usually applied in automotive and aerospace industries where flexibility and longevity are important. It also has outstanding electrical insulating properties where applying strict performance standards are critical. It is also a suitable material for parts that need FDA approval for food handling equipment and appliances.
