Single hydroxyl group HTPB CAS 69102-90-5 Hydroxyl-terminated polybutadiene HTPB with a single chain of hydroxyl -OH and hydrogenated version

Short Description:

HTPB is a liquid remote claw polymer, the new liquid rubber. The properties vary because HTPB is a mixture rather than a pure compound, and it is manufactured to meet customers’ specific requirements. A typical HTPB is R-45M with each end of the chain terminated with a hydroxyl [OH] group. ( PS: we can do new design as the HTPB with a single -OH per chain).

Meanwhile, we can do hydrogenation of the HTPB.

Features

HTPB is a liquid remote claw polymer, the new liquid rubber. The properties vary because HTPB is a mixture rather than a pure compound, and it is manufactured to meet customers' specific requirements. A typical HTPB is R-45M with each end of the chain terminated with a hydroxyl [OH] group. (PS: we can do any versions of HTPB as customers request, and new design the HTPB with a single chain of hydroxyl -OH, Meanwhile, we can do hydrogenation of the HTPB)

The single hydroxyl group HTPB is a polybutadiene product with hydroxyl groups at one end, which can achieve double curing of hydroxyl and vinyl groups. It has high reactivity, excellent hydrophobicity and dielectric properties, and good processing performance.

Applications

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

- lubricating oils

- and so on many kinds of usage.

Packing & Storage

Packing:

Packed in 50kg/drum, 170kg/drum, The storage period is 1 year.

Safety instructions:
