高粘度TPV 8211-55B100

高粘度TPV 8211-55B100--It is a soft, colorable, special nonhygroscopic thermoplastic vulcanized elastomer (TPV) in thethermoplastic elastomer (TPE) series. It is specially formulatedfor bonding with ABS, PS, PC, PMMA, ASA, pet and PPO / PS Blendsand is suitable for applications requiring a combination of hard /soft materials

TPV 8211-55B100它是热塑性弹性体（TPE）系列中的一种软质、可着色、特种非吸湿性热塑性硫化弹性体（TPV）。它专门配制用于与 ABS、PS、PC、PMMA、ASA、PET 和 PPO/PS 共混物粘结，适合于要求硬/软材料组合的应用

研究表明，因为塑胶相和橡胶相的本质分子结构特点不一样，可塑性相构成的提升造成TPV的抗拉强度提升但拉伸强度降低。近些年，有关构成核对TPV物理性能的不良影响的分析主要是聚集在新式TPV管理体系上，如生物基TPV，Kang等人科学研究了BPE成分对生物基聚脂弹性体材料（BPE）/PLA-TPV的抗拉强度和强度的危害，研究表明，伴随着BPE成分的提升BPE/PLA-TPV的抗拉强度和强度降低。当BPE成分提升到80wt%时，因为高成分BPE颗粒物在PLA基材中的分散化不匀称，TPV的拉伸强度值也随减少

The research shows that because the essential molecularstructure characteristics of plastic phase and rubber phase aredifferent, the improvement of the composition of plastic phaseleads to the increase of the tensile strength of TPV, but thetensile strength decreases. In recent years, the analysis of theadverse effects on the physical properties of TPV mainly focused onthe new TPV management system, such as bio based TPV. Kang andothers scientifically studied the harm of BPE composition to thetensile strength and strength of bio based polyester elastomer(BPE) / pla-tpv. The research showed that with the increase of BPEcomposition, the tensile strength and strength of BPE / pla-tpvdecreased. When the BPE composition is increased to 80 wt%, thetensile strength value of TPV also decreases due to the unevendispersion of high-component BPE particles in PLA substrate
