Description
HTPB crosslinks to isocyanate to form Elastomer (rubber), which has excellent water resistance, chemical resistance, and electrical properties because its parent is a hydrocarbon. In particular, it has excellent mechanical properties and excellent reproducibility during product molding, so it is used in many industries, including high-performance propellant binders.
Features
- High reactivity: Alllyl type has the first class hydroxyl group
- Excellent chemical resistance (acid and alkali) and water resistance
- Excellent rubber elasticity: 1,4-bonding 80%
- Effective reinforcement is possible: Easy reinforcement with carbon black, white carbon, etc
- OIL-EXTENSION is possible: Compatibility with Process Oil, Asphalt, etc. is good
- Excellent low temperature resistance: The saturated temperature of the cured product is -70°C or less.
- It has excellent electrical properties: It has electrical insulation and dielectric properties, and has less temperature dependence, hygroscopicity, and hygroscopicity
- A wide range of physical properties can be adjusted: Applicable in a variety of ways from soft to hard types
Applications
- Rocket propellant binders, insulation coding agents in the field of electrical and electronic materials, automotive materials, etc.
