| Abstract: |
| The influence of curing system，addition level of curing agent and crosslink density on the Shore A hardness，compression stress and flexibility of silicone rubber vulcanizates was investigated.The results showed that，the Shore A hardness and compression stress of silicone rubber vulcanizates were increased as the addition level of curing agent increased；the flexibility of silicone rubber vulcanizates by using addition type curing system was better compared with that by using peroxide curing system when silicone matrixes were the same；the flexibility of silicone rubber vulcanizates was better as the molecular weight of matrix rubber and crosslink density were lower when addition type curing system was used. |
