Hydroxyl-terminated polybutadiene（HTPB）

Hydroxyl-terminated liquid polybutadiene (hydroxybutadiene rubber, HTPB) is a liquid telechelic polymer and a new type of liquid rubber. It reacts with chain extenders and cross-linking agents at room temperature or high temperature to form a cured product with a three-dimensional network structure. The cured product has excellent mechanical properties, especially hydrolysis resistance, acid and alkali resistance, wear resistance, low temperature resistance and excellent electrical insulation properties.
