What is Polybutene CAS 9003-28-5？

Polybutene is a polymer inert polymer, mainly made from the polymerization of butene, is a polymer homopolymer. Compared with other polyolefins, it is rigid. High tensile strength. Good heat resistance. Resistant to chemical corrosion in oils, detergents and other solvents, does not produce embrittlement like other plastics such as HDPE. Embrittlement occurs only under strong oxidants such as 98% concentrated sulfuric acid. Excellent creep resistance. It has the same wear resistance as ultra high molecular polyethylene.

Application

Polybutylene is often used as a plasticizer, binder, chemical intermediate for gasoline additives, and sealant. Although polybutylene has been found to improve properties such as adhesion, rust prevention and water resistance in paints, it is also often used in the formulation of cosmetics such as lipsticks.
