HYDROXYL-TERMINATED POLYBUTADIENE(HTPB)

Terminal hydroxyl liquid polybutadiene (referred to as butyl hydroxyl rubber, abbreviated as HTPB) is a liquid remote claw polymer, a new type of liquid rubber.
It reacts with a chain extender and cross-linking agent at room temperature or high temperature to generate a three-dimensional network structure of the cured substance.
