ENEOS Polyisobutylene HV-300 and HV-1900

ENEOS Polyisobutylene

ENEOS Polyisobutylene is a copolymer consisting mainly of isobutylene with some butene, forming long-chain hydrocarbon molecules. It is generally highly stable, colorless, transparent, free of impurities, non-toxic, and liquid.

Applications

○ Lubricating oils, including compressor oils, lubricant additives, and engine fuel additives
○ Electrical insulating oils
○ Carbon and cable compounds
○ Adhesives
○ Modifiers for rubber, wax, asphalt, and other materials
○ Tackifiers and dispersants for coatings
○ Plasticizer for chewing gum
