This specification covers a silicone (VMQ) rubber in the form of sheet, strip, and molded shapes. Primarily for parts required to operate or seal from -55 to +200 degrees C (-67 to +392 degrees F), compounded especially for low compression set. Silicone rubber is resistant to deterioration by ozone, smog, and weathering and remains flexible over the temperature range noted. These products are not intended for use with petroleum-base fluids or lubricants. Certain design applications may cause these products to be susceptible to cutting, tearing, and abrasion.
