硫化胶的屈挠疲劳性能是对动态条件下应用的制品,如轮胎、胶带、减震制品和动态密封制品等的使用性能和产品质量具有决定性影响的因素之一。在静态使用过程中,硫化胶会因蠕变、应力松弛和永久变形的积累而产生形变,从而导致性能下降,动态条件下此种情况更甚。反式异戊二烯橡胶(TPI)的诞生曾一度引起橡塑界的轰动,并有大量关于TPI的研究报道。继TPI之后,新的改性材料R-TPI的问世大有可能为橡胶行业 Flexural fatigue properties of vulcanizates are one of the factors that have a decisive influence on the serviceability and product quality of products applied under dynamic conditions, such as tires, tapes, shock-absorbing products and dynamic sealing products. During static use, vulcanizates can deform due to creep, stress relaxation and permanent set-up, resulting in reduced performance, even under dynamic conditions. The birth of trans-isoprene rubber (TPI) was once caused a sensation in the rubber and plastics industry, and a large number of TPI research reports. Following the TPI, the advent of the new modified material R-TPI is likely to be the rubber industry
