PVC thermoplastic elastomer (TPVC) was prepared by plasticization, blending and compounding of high polymerization degree PVC, and its impact resilience and compression properties were investigated.
Other technical properties such as resilience and compression set have also been evaluated and are found to be better than 3-5 PHR oil plasticized NR vulcanizates.
In order to meet steady compression -resilience properties as cylinder gasket, the thickness tolerance of composite sheet and the density of flexible graphite plate should be control.
