促使改善汽车发动机罩内弹性体的使用性能有多种重要因素,这里将着重讨论下述几种因素:发动机的高温、腐蚀性较大的油添加剂、氧化和酸性燃油、由于采用新工艺使设计更改以及较长的安全和质量保证期等。为满足上述的要求,预计氟橡胶(FKM)的用量即使在要求降低成本的压力下也会越来越大,特别是一些含氟量较高的FKM、能够改善低温屈挠性的弹性体,及不常使用的单体聚合物和硫化体系。为满足航空工业对高使用性能的密封弹性体的需求,在50年代商业上就推出了Vit-
There are several important factors that contribute to improving the serviceability of elastomers in automotive hoods. Here are a few key factors to consider: High temperature, corrosive engine oils, oxidising and sour fuels, engineered designs Changes and longer safety and quality assurance periods. In order to meet the above requirements, it is expected that the amount of fluororubber (FKM) will increase even under the pressure to reduce the cost. In particular, some FKM with high fluorine content, elastomers capable of improving low temperature flexibility, And infrequently used monomeric polymers and vulcanization systems. In order to meet the aviation industry’s demand for high-performance sealing elastomers, Vit-Pro introduced the Vit-
