Silicones

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.

As well as millable grade silicones, Minnesota Rubber and Plastics offers Liquid Silicone Rubber (LSR) molding. The LSR process offers design, cost and end-use options that complement and extend beyond the capabilities of millable grade materials. Minnesota Rubber and Plastics offers LSR compounds with hardness from 20 to 80 Shore A in different colors. Learn more about our LSR capabilities.
