Hydroxyl-terminated polybutadiene
Other name : HTPB
CAS RN. 69102-90-5
HTPB is a liquid remote claw polymer,,the new liquid rubber.It and chain extension agent, crosslinking agent in room temperature or high temperature reaction can generate 3 d network structure of curing content.The curing content has excellent mechanical properties, especially good resistance to hydrolysis, acid and alkali resistant, wear resistance, low temperature resistance and excellent electrical insulation.
