Butyl Rubber

INQUIRE

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.

We provide our customers with everything from material sampling and product prototyping to full manufacturing, packaging, and delivery. We provide value to our customers by delivering exceptional customer service, engineering solutions, and quality products to meet their every need.

Butyl sheet rubber is available in the following formulations:

Durometer Thickness Width Tensile PSI Ultimate Elongation % Temperature Range Specifications
40 1/32 – 1/4 36, 48 1100 550 -40°F to +180°F ASTM D 2000
