| Abstract: |
| The effective factors on the curing characteristics of silicone rubber（MPVQ）foam prepared with the technology of removing temporary filler were investigated.The results showed that the activators[zinc oxide whisker and N，N’-m-phenylene bismaleimide（HVA-2）]could reduce the optimum cure time of MPVQ foam at high temperature，but had little effect of accelerating cure of MPVQ foam at low temperature；the MPVQ foam tended to be cured slowly during the storage at room temperature and the up to 5 days storage at room temperature didn’t have adverse effect on the final cure state of MPVQ foam，but the residual treating agent on spherical blowing agent did. |
