Usage
Pressure-sensitive adhesive (PSA): Provides durable adhesion, aging resistance, and low-temperature flexibility; used in packaging tapes, medical patches, labels, etc.
Viscosity index improver: Enhances the high-temperature viscosity stability of lubricating oils; suitable for engine oils, gear oils, hydraulic oils, and high-temperature chain oils.
Butyl rubber (IIR) raw material: Copolymerized with isoprene to manufacture inner tubes, vulcanized bladders, and medical bottle stoppers, highlighting airtightness and aging resistance.
Rubber modifier: Improves the processability, flexibility, and airtightness of natural/synthetic rubbers; used in tire liners, hoses, and seals.
Plastics modification: Blended with PE/PP to improve impact resistance and stress cracking resistance; used in pipes and films.
