Polyisobutylene(PIB)

Chemical formula: (C4H8)n; Purity: 99%

The finished product is colorless to light yellow viscous liquid or elastic rubber-like semi-solid (low molecular weight is soft gelatinous, high molecular weight is tough and elastic), tasteless and odorless. Low and medium molecular weight polyisobutylenes are used as oil additives, rubber additives, sealants, coatings, lubricants, plasticizers and cable impregnants.High molecular weight polyisobutylene is added to natural rubber or styrene-butadiene rubber to improve the aging resistance, weather resistance, flexural fracture resistance, ozone resistance, and dielectric properties of rubber at high temperature, and reduce its absorption of water and permeability to gas .It can be used for the lining of fuel tanks, pipelines and other containers or various vehicle tires. Adding a small amount of high-weight polyisobutylene at 6-10 ºC above the melting point of the plastic can greatly improve and improve the impact strength, tear strength, tensile-fracture performance, barrier performance, flexibility and resistance to acid, alkali, and intoxication of polyolefin. erosion, etc.

Packaging: net weight 175, 180kg/iron drum
