Thermoplastic polyurethane elastomer properties and applications

Not necessarily intrinsically linked. Can be the catalyst of the formula and the adjustment of the burning rate to optimize the combustion performance. Avoid cross-linked composite modified double base propellant burning rate pressure exponent. 4 Conclusion a) prepared a series of TPUE, and nitrate ester with good or very good compatibility, with excellent mechanical properties, especially the low-temperature mechanical properties of propellant or gunpowder is to improve the mechanical properties of the material of choice; b) The results show that TPUE content appropriate, TPUEC similar system and rubber toughened plastics, rrPuE toughening effect, will help to improve the low temperature mechanical properties of cellulose nitrate; C) TPUE used nitramine modified double base propellant, it is clear improve process performance and mechanical properties, so that a wider range of adjustment formula is expected to prepare a higher solid content of the modified double base propellant References [1] CohenN.
