Product details
HTPB / Hydroxyl-terminated polybutadiene CAS: 69102-90-5
Product details:
Chemical Name: Hydroxyl-terminated polybutadiene
CAS: 69102-90-5
Character: manufacturer
Standard: GB / GJB
Product properties
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 3D 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.
Application
HTPB has good diaphaneity,low viscosity, ageing resistance, low temperature performance, Hydrolysis resistance, acid and alkali resistance, wear resistance and excellent electrical insulation properties
and processing performance is good. HTPB can be used in :
- Adhesive
- Sealents
- Polymers
- Electrical insulation materials
- Waterproofing and corrosion protection materials
- Coating
- Polyurethane materials
- Rubber products
- Solid fuel
- Propellant
- Car and Planes tires of structural materials
- Hydroxyl-terminated polybutadiene propellant(HTPB+AP+Al)
- Aerospace, Rockets and Missile
- and so on many kinds of usage.
