Product Description
Product Details
Introduction
Terminal hydroxyl liquid polybutadiene (referred to as butyl hydroxyl rubber, abbreviated as HTPB), is a liquid remote claw polymer, is a new type of liquid rubber.
It reacts with chain extender and cross-linking agent at room temperature or high temperature to generate a three-dimensional network structure of the cured substance.
Cured Substance Features
·Hydrolysis resistance
·Acid and alkali resistance
·Abrasion resistance
·Low temperature resistance
·Excellent electrical insulation.
Application
Liquid Hydroxyl-terminated polybutadiene can be used in the production of cast elastomers, used as structural materials for automobile and aircraft tires, construction materials, footwear materials, rubber products, thermal insulation materials, coatings, adhesives, potting materials, electrical insulation materials, waterproof and anticorrosive materials, sports runways, abrasion-resistant transport belts, modification of rubber and epoxy resins, and other various applications.
