More About VMQ


  • Silicone rubber is an elastomer (rubber-like material) composed of silicone together with carbon, hydrogen, and oxygen.
  • Silicone rubbers are widely used in industry, and there are multiple formulations.
  • Silicone rubbers are often one- or two-part polymers, and may contain fillers to improve properties or reduce cost.
  • Silicone rubber is generally non-reactive, stable, and resistant to extreme environments and temperatures from -55 °C to +300 °C while still maintaining its useful properties.

Due to these properties and its ease of manufacturing and shaping, silicone rubber can be found in a wide variety of products, including:

  • Automotive applications
  • Cooking, baking, and food storage products
  • Apparel such as undergarments, sportswear, and footwear
  • Electronics
  • Medical devices and implants
  • In home repair and hardware with products such as silicone sealants
