Chemical Name : Polyisobutylene
CAS Number : 9003-27-4
Appearance :Semisolid substance
Molecular Formula : C4H8
Uses: Polyisobutylene (PIB) is a colorless, odorless and nontoxic viscous or semi-solid substance, which has good chemical properties such as heat resistance, oxygen resistance, ozone resistance, weather resistance, ultraviolet resistance, acid resistance and alkali resistance. It has very important applications in the fields of lubricating oil additives, polymer materials post-processing, pharmaceuticals, cosmetics and food additives, etc. Among them, PIB with low molecular weight can be used to produce ashless dispersant adhesives, sealants, humectants for pharmaceuticals and cosmetics, etc. PIB with medium molecular weight is mainly used as chewing gum base, insulating glass sealing material and agricultural pesticide.
