Polyisobutylene Uses
- Lubricating oil additives are widely used in lubricating oil ashless dispersants. Ashless dispersants are produced using a thermal addition process during the production process. Compared with the products produced by chlorination method, it has better oxidation resistance and dispersion.
- Adhesive: Polyisobutylene is mainly used as pressure-sensitive adhesive tackifier and self-adhesive adhesive. Such as packaging bags, insulation tapes, high-quality sealants, and sealing strips. It is widely used in plastic modified films in construction, vehicles and refrigerators.
- Electrical insulation materials and protective films. It can be used as insulating oil for electrical equipment, cable materials and capacitor oil. It can be blended with paraffin and asphalt to form moisture-proof sealing material for induction coils.
- Polymer modification: Polyisobutylene PIB Additive is miscible with other materials to make a variety of waterproof sealing films, such as protective films applied to the top of cars, waterproof sealants in the construction industry, and roof waterproof sealing layers.
