Polybutene has unique properties and is widely used in different fields:
(1) adhesives (including pressure sensitive adhesive) : polybutene is widely used in different types of adhesive formulations, such as pressure sensitive adhesive (PSA) and hot melt adhesive (HMA). Due to the non-toxic and high transparency of polyisobutylene, this material is also widely used in automobiles. Refrigerator waterproof sealant field. High molecular weight polyisobutylene and polyethylene together as cable coating, can also be used in waterproof adhesive, waterproof stone, wax paper and hot melt adhesive.
(2) electrical insulation: polyisobutylene and natural rubber, as well as synthetic rubber (butyl rubber); When mixed, Polyisobutylene is also used for insulation and corrosion protection of wire and communication cables.
(3) waterproof material: it can be made into elastic waterproof roll, waterproof film, waterproof coating, coating material, as well as oil paste and glue Sealing materials, such as mud, waterproof tape, etc. These products have high tensile strength, high elasticity, high elongation, adhesion, Good water resistance and weather resistance, can be used cold, longer service life.
(4) Viscosifier: used to improve the viscosity of oil products, improve the viscosity-temperature characteristics, to meet the wide temperature range of oil viscosity requirements. It is mainly used for mixing multistage internal combustion engine oil, also for automatic variable speed engine oil and low temperature hydraulic oil.
(5) Sealant: polyisobutylene have excellent resistance to the atmosphere, the characteristics of the ageing resistance and durability, and also has low moisture penetration rate and do not produce smoke, fog is very applicable from the glass sealant, double glass door, window sealant.
(6) Adhesive tape: good weather resistance > NR, viscosity < Span = \"\" & gt; , no residue > Acrylic, low polarity & lt; Span = \"\" & gt; , low water transmittance, high strength after bonding and wide applicable temperature range > Acrylic/rubber to make it widely used in adhesives industry.
(7) Wrapping film: the wrapping film can improve its tensile rate, tear strength, impact strength, stickiness and softness.
(8) the surface of the print processing: processing surface on the surface of printed matter is the appropriate treatment, increase the luster of the print, or increase the light fastness of printed matter, heat resistance, water resistance, abrasion resistance, protect the printed matter.
(9) food additives: daline polyisobutylene can be used as the basic agent of chewing gum.
(10) Capacitor: dalin polyisobutylene can be used as a mixture of electrical insulation material, capacitor impregnation oil and battery insulation
