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
