Butyl Rubber


Butyl Rubber Custom Fabricated To Your Exact Specifications – Gaskets, Seals, Pads and More

SRP is a leading converter of sheet rubber materials such as butyl rubber. We manufacture high-quality custom Butyl gaskets, seals, and other products for a variety applications and industries to companies around the world.

Butyl (also known as Isobutylene-isoprene) is impermeable to air and used in many applications requiring airtight seals. Butyl rubber has outstanding resistance to:

  • Gases
  • Vapors
  • Heat aging
  • Oxygen
  • Ozone
  • Sunlight
  • Abrasion
  • and Tearing

Butyl rubber also has excellent resistance to alkalis and acids and is good for electrical insulation. It has a temperature range of -49°F to + 302°F. Butyl Rubber has a very low resilience, which makes it ideal for vibration damping and shock absorption applications, but offers only a moderate resistance to abrasion and compression. All butyl sheet rubber products can be supplied with Pressure Sensitive Adhesives.

Butyl rubber is available in the following formulations:

Durometer:Thickness:Width:Tensile:Elongation:Temperature Range:Specs:
401/32" – 1/4"36", 48"1100550-40°F to +180°F ASTM D 2000
501/32" – 1/4"36", 48"1100400-40°F to +180°F ASTM D 2000
601/32" – 1/4"36", 48"1100300-40°F to +180°F ASTM D 2000
