The hardness of this VMQ (Vinyl Methyl Silicone) O-ring is 80 Shore A. This VMQ O-Ring - 80 Shore A can handle temperatures from -60 °C to +200 °C. You can achieve +230 °C with special qualities. The color of the VMQ O-ring is red.
Dow Corning (a collaboration between Dow Chemicals and Corning Glass Company) was the first to produce silicone rubber. A few years later in 1947 General Electric also started the production of silicone rubber. They patented their production method. VMQ O-rings are a group of elastomeric materials made from silicones, oxygen, hydrogen, and carbon. As a group, silicones have poor tensile strength, tear-resistance, and abrasion resistance. Special compounds have been developed with exceptional resistance to heat and pressure changes. High-strength compounds have also been made, but their strength is not comparable to conventional rubber.
