<，延伸率提高。推进剂的机械性能可以满足要求，但为了确保足够的机械强度，高能增塑剂的用量不应太大。当然，配方的进一步优化将使配方的整体性能更加优异。（1） 理论比冲计算结果表明，以合成TPU塑料为粘结剂制成的复合固体推进剂具有较高的能级，与TPU推进剂大致相当。（2） TPU热塑性复合固体推进剂是以合成的热塑性聚氨酯弹性体为粘结剂，采用溶解、吸收、压延和压缩等工艺制备的。（3） 所制备的热塑性复合固体推进剂具有较高的理论比冲，可高于265s，具有优异的燃烧性能和良好的力学性能。然而，增塑剂的用量对机械性能有显著影响，不宜过大。（4） 初步研究表明，该推进剂是一种值得研究和开发的推进剂。TPU加玻璃纤维材料是PVC在医疗器械制造中的替代品：由于TPU的强度明显高于PVC和其他替代材料，因此可以制成具有更高内压阻力的薄壁导管和医疗袋。TPU制造的医疗器械不仅结构更精确，材料更少，而且在频繁使用的医疗环境中制造的医疗器械损坏的可能性更低。与其他潜在的PVC替代材料如EVA和TPO相比，TPU也具有更好的透明度，这可以确保其不低于PVC的美观性。总之，TPU是医疗器械中PVC的良好替代品

Product Details

TPU plastic glass fiber

With the increase of ester content, the tensile strength of TPU plus glass fiber propellant decreases greatly, and the elongation rate is increased. The mechanical properties of the propellant can be satisfied, but in order to ensure sufficient mechanical strength, the amount of energetic plasticizer should not be too large. Of course, further optimization of the formula will make the overall performance of the formula more excellent. (1) The theoretical specific impulse calculation results show that the composite solid propellant made of synthetic TPU plastic as a binder has a higher energy level, which is roughly equivalent to that of TPU propellant. (2) TPU thermoplastic composite solid propellant was prepared by using synthetic thermoplastic polyurethane elastomer as a binder as a plasticizer, and using processes such as dissolution, absorption, calendering, and compression. (3) The prepared thermoplastic composite solid propellant has a high theoretical specific impulse, which can be higher than 265s, and has excellent combustion performance and good mechanical properties. However, the amount of plasticizer has a significant impact on the mechanical properties and should not be too large. (4) Preliminary research shows that the propellant is a type of propellant that is worthy of research and development. TPU plus glass fiber material is a substitute for PVC in the manufacture of medical devices: because the strength of TPU is significantly higher than that of PVC and other alternative materials, it can be made into thin-walled guide and medical bags with higher internal pressure resistance. The structure of medical devices made of TPU is not only more accurate, with less materials, but also the possibility of damage to the medical devices made in the frequently used medical environment is lower. Compared with other potential PVC substitute materials such as EVA and TPO, TPU also has better transparency, which can ensure that it is not inferior to the aesthetics of PVC. In summary, TPU is a good substitute for PVC in medical devices.
