What is Polyisobutylene(PIB) CAS 9003-27-4?
Polyisobutylene (PIB) is a colorless, tasteless, non-toxic thick or semi-solid substance, heat resistance, oxygen resistance, ozone resistance, weather resistance, ultraviolet resistance, acid and alkali resistance and other chemicals good performance. The average molecular weight is 200,000 ~ 87 million. Soluble in benzene and diisobutylene, can be miscible with polyvinyl acetate, wax, etc., insoluble in water, alcohol and other polar solvents. It can make gum sugar have excellent softness at low temperature, and has certain plasticity at high temperature to make up for the shortcomings of polyvinyl acetate when it is cold, hot weather and excessive softening when it meets mouth temperature.

Application
- Lubricant additives: Polyisobutylene has excellent frying and cutting stability, suitable oxidation stability and high temperature detergency, can increase the thickness and strength of the oil film, and plays the role of viscosity increase, pour point reduction and vibration reduction in lubricating oil, thereby improving lubrication performance and extending the service life of mechanical equipment.
- Rubber modification: PIB can be used for rubber modification to improve the aging resistance, plasticity and air tightness of rubber. It has good compatibility with rubber and can form a stable network structure in rubber, thereby improving the performance and service life of rubber products.
- Paraffin mixing: Poly isobutylene can be mixed with paraffin or microcrystalline wax to increase its tensile properties and improve the brittleness of the product, making the packaging of frozen food more flexible and acid-resistant.
- Sealant and adhesive: Polyisobutene has excellent atmospheric resistance, aging resistance and weather resistance, and is very suitable for the production of various sealants and hollow glass sealants. At the same time, it can also be used as a tackifier for pressure-sensitive adhesives and sealants to improve their adhesion.


Storage considerations
- Storage environment: Store Polyisobutylene in a cool, dry, well-ventilated place to prevent heat and moisture absorption. Avoid direct sunlight to avoid affecting its performance.
- Keep away from heat and fire sources: Keep away from fire and heat sources, such as open flames, heating equipment, etc. Poly isobutylene may release flammable gases at high temperatures, which may cause fire and explosion.
- Store separately: Store separately from oxidants and edible chemicals to prevent chemical reactions and ensure product quality and safety.
- Container sealing: Keep the container sealed to prevent air from entering, avoid possible oxidation or other reactions, and also help prevent the release of volatile components.
