What We Offer

Polyisobutylene has excellent heat resistance, ultraviolet resistance, ozone aging resistance, gas and moisture barrier properties, and can maintain a certain flexibility at low temperatures.
Polyisobutylene can be widely used in oil additives, roofing membranes, insulation tape, sealants, adhesives, protective films, chewing gum, wax modification and so on.
High molecular weight polyisobutylene is a rubbery elastomer with a molecular weight (Mv) of >100,000.
Polyisobutylene is virtually tasteless and odor-free.
Polyisobutylene displays cold flow, and undergoes permanent deformation under a permanent load.
Polyisobutylene has very low permeability to gases such as Argon, water or aqueous solutions.
The glass transition temperature of polyisobutylene is -64℃, and it can still maintain elasticity at -50℃.
