Hydroxyl-terminated polybutadiene

天元航材是一家生产销售端羟基聚丁二烯(HTPB、Hydroxyl-terminated polybutadiene)等化工原材料的厂家,其中端羟基聚丁二烯的英文名称为Hydroxyl-terminated polybutadiene,端羟基聚丁二烯是一种液体遥爪聚合物,是一种新型液体橡胶。那么您足够了解Hydroxyl-terminated polybutadiene吗?今天小编给大家介绍一下吧!

Hydroxyl-terminated polybutadiene

Hydroxyl-terminated polybutadiene (HTPB) is an oligomer of butadiene terminated at each end with a >hydroxyl functional group. It reacts with isocyanates to form polyurethane polymers.

HTPB is a translucent liquid with a color similar to wax paper and a viscosity similar to corn syrup. 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-45HTLO. This product consists of oligomeric units typically containing 40–50 butadiene molecules bonded together, with each end of the chain terminated with a hydroxyl [OH] group.

R-45HTLO has a functionality of 2.4-2.6, which means that there is (approximately) one additional hydroxyl group located along the chain for every two oligomeric units. This provides side-to-side linkage for a stronger cured product. HTPB is usually cured by an addition reaction with di- or poly-isocyanate compounds.
