SILICONES (VMQ, PMQ, PVMQ)
Extreme temperature range stability and low temperature flexibility are characteristics of silicone compounds. Silicones provide outstanding resistance to compression set, sunlight, ozone, oxygen, and moisture. They are very clean and are used in many food and medical applications because they do not impart odor or taste.
Silicone can be compounded to be electrically resistant, conductive or flame retardant.
