Abstract
The influence of bisphenol AF and BPP on the low temperature properties of fluoroelastomer 2462 was investigated.The results showed that MH of rubber matrix was increased with the increasing of bisphenol AF.And the intensity changed unobviously.The compression set of the vulcanizate was decreased.Its brittle temperature showed a downward trend.Also the scorch time and tc90 were shortened with the increasing of BPP.The compression set of the vulcanizate was increased and the brittle temperature was elevated.As BPP on the improvement of cross-linking density was very little,the mechanical properties of the vulcanizate did not change significantly.
