99% Hydroxyl-terminated polybutadiene

Hydroxyl - terminated polybutadiene (HTPB) is a kind of liquid rubber, which is widely used in the chemical industry.
Chemical Structure: It is synthesized from 1,3 - butadiene monomers through anionic polymerization. Both ends of the molecular chain are equipped with hydroxyl active groups, enabling it to react with a variety of substances.
Physical Properties: Typically, it is a colorless to light yellow transparent viscous liquid, possessing excellent flexibility, low - temperature resistance, and hydrolysis resistance.
Main Applications: In the aerospace field, it serves as a crucial binder for manufacturing composite solid propellants, which can enhance the mechanical properties and stability of propellants. In the rubber industry, it can be used to produce high - performance rubber products, improving the processing and physical properties of rubber. In the coating and adhesive industries, as a raw material, it can enhance the adhesion, flexibility, and corrosion resistance of products.
Safety: It is relatively stable under normal temperature and pressure and has low toxicity. However, during production and use, it is necessary to avoid contact with strong oxidants. Operators should also take appropriate protective measures to avoid direct contact.
