SOLID SILICONE SHEET

COMMERCIAL, Food, MILITARY Grades

Our series of solid silicone sheet are constructed using a high silicone polymer mixture which translates to exceptional performance across all durometers. Designed with a long service life in mind, these materials provide excellent resistance to chemicals, fluids, and extreme temperature environments. Manufactured in continuous rolls, in three grades, with a smooth surface finish on both sides.

Solid silicone Sheet Benefits

In general, solid silicone sheet offers users a non-toxic, long lasting, high performance material. Able to operate in extreme temperatures it also possesses excellent weathering, oxidation and ozone resistant characteristics. As such, it is an ideal choice for seals and gaskets where a premium solid sheet material is needed.

  • Food Safe – through raw materials and proper processing solid silicone sheet can be FDA approved.
  • Ozone & UV Resistant – very good weathering properties makes it an ideal choice for outdoor applications.
  • Temperature Resistant – excellent material for extreme hot or cold applications.

Solid silicone Sheet Applications

Solid silicone sheet can be converted or fabricated into many products. These end uses typically require materials that are quality consistent, dependable and can deliver outstanding performance while meeting critical safety standards in harsh working environments. For solid silicone sheets, such as ours, potential end uses can include:

  • Automotive – seals & vibration damping pads
  • Construction – gaskets, seals & vibration damping pads
  • Food & Beverage – gasket & seals
  • Led Lighting – gaskets, strips, seals & vibration damping pads
  • Mass Transit – insulation & vibration damping pads
  • Oil & Gas – gaskets, insulation & seals
