What is VMQ Silicone (Polymethyl-Vinyl-Siloxanes)?

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.

What is VMQ Silicone O-rings used for?

  • Medical industry
  • Farmaceutical industry
  • Food industry

The advantages of an O ring from VMQ Silicone:

  • It has a temperature working range from -40 °C to +200 °C
  • Even at high temperatures, its characteristics won’t be affected
  • Resistant to bacteria and fungi
  • Excellent resistance to chemical fluids

The disadvantages of an O-ring from VMQ Silicone:

  • Low resistance against mineral oils
  • Not resistant to (aromatic) hydrocarbon, based fuels, and strong acids and alkalis
  • It’s known for its mechanical weakness
  • Sensitive to shear forces and therefore not suitable for dynamic or rotary closure application
