Butyl

A copolymer of isobutylene and a small amount of isoprene,Butyl has largely been replaced by propylene since its introduction.

Key Use:

Highly effective in Vacuum sealing applications. Good seal for hydraulic systems.

Working Temperature Range: - 40 °F to + 250 °F. (Dry Heat Only.)

Features:

• With outstanding low permeability to gases, Butyl is especially effective in vacuums sealing applications. It also features good to excellent resistance to ozone and sunlight aging.
• Butyl further features excellent shock dampening capabilities.
• Only slightly affected by oxygenated solvents and other polar liquids, Butyl is often Utilize in seal for hydraulic systems using synthetic fluids.
