Product Description
Hydroxyl-Terminated Polybutadiene (HTPB) CAS 69102-90-5
Hydroxyl-terminated polybutadiene is a liquid prepolymer that can be transformed into an elastomer with a three-dimensional network structure through chain extension and cross-linking curing reactions. With properties comparable to solid rubber, it is also referred to as liquid rubber. The cured material exhibits exceptional mechanical properties, including outstanding hydrolysis resistance, acid and alkali resistance, abrasion resistance, low temperature performance, and excellent electrical insulation capabilities.
Key Benefits
- Excellent Hydrolysis Resistance
- Superior Acid and Alkali Resistance
- High Abrasion Resistance
- Excellent Low Temperature Resistance
- Excellent Electrical Insulation Properties
Target Industries & Applications
Adhesives, Coatings, Sealants, and other Polymer applications.
