It contains no dielectric and has excellent electric insurability and there is no residue after heating. It is well compatible with polyethylene and paraffin wax, etc. It is soluble in organic solvents like gasoline and benzene but not water and alcohol types of solvents, with nice shearing stability.Main Applications: 1)Lubricating Oil Additive:Polyisobutylene has stable chemical property, and contains fewer impurities than mineral oil. It can be used either as lubricating oil separately or as composite lubricating oil, thus it is obvious that polyisobutylene has a brighter development prospect in the lubricating oil industry. 2)Electric Insulation:Polyisobutylene has an excellent electric insulation property,it can be used as the electric insulating material. 3)Adhesive Additive:Poly-isobutylene can be used as a binding agent for sticker and pressure sensitive adhesive.
