Butyl rubber

What is Butyl Rubber?
Butyl Rubber is a material made to absorb shock.

Butyl rubber offers special capabilities to make it a potential choice for quality sealing, ester, installation or other tasks. In addition to excellent shock absorption, this tire has very low gas permeability and moisture

And has excellent resistance to heat, weather, ozone, chemical reaction, flexibility, wear and tear. Butyl is also resistant to phosphate-based hydraulic fluids and has excellent electrical insulation performance.
