Molecular formula :
CAS :
nature : based on thermoplastic elastomers (TPEs) for the solid propellant binder. Thermoplastic elastomer is a scheduled temperatures can be a physical crosslinking block or graft copolymer. These physical crosslinking is reversible when the temperature higher than the expected temperature, TPEs can flow into the liquid. Instead, as the resumption of solid elastomer. For example, polybutadiene - polystyrene block copolymer, poly THF-block copolymer poly Citation other. Manufacturing methods are solvent, melt mixing casting method and dry materials mixed heating pressurized vacuum melting law. With the increase in the propellant simple process, performance reproducible and easier to control quality, corner I expected to be used and the advantages of lower cost.
