Butyl

Butyl is a copolymer of isobutylene and isoprene. Butyl is highly effective in vacuum sealing applications. Desirable properties include exceptional low gas permeability and outstanding resistance to heat, ozone, chemical attack and tearing.

Butyl is ofter utilized in seals for hydraulic systems using synthetic fluids, M.E.K., and silicone fluids and greases with excellent shock dampening capabilities.
