High polymer butyl rubber

WebButyl Butyl rubber is extremely resistant to gas, water, and steam permeation. Butyl rubber is readily available as an elastomeric waterproofing membrane or tape. If you need water resistance, butyl adhesives, liners, and seals should be at the top of your list. Butyl adhesives are less temperature-sensitive than natural rubber. EPDM Isobutylene was discovered by Michael Faraday in 1825. Polyisobutylene (PIB) was first developed by the BASF unit of IG Farben in 1931 using a boron trifluoride catalyst at low temperatures and sold under the trade name Oppanol B [de]. PIB remains a core business for BASF to this day. It was later developed into butyl rubber in 1937, by researchers William J. Sparks and Robert M. Thomas, at Standard Oil of New Jersey's Linden, N.J., laboratory. Today, the majority of the globa…
