Application of Plasticizers in Chlorosulfonated Polyethylene Rubber
The effects of plasticizer DOP,DOS and chlorinated paraffin on the properties of chlorosulfonated polyethylene rubber(CSM) were investigated.The results showed that,as the addition level of plasticizer increased,the Mooney viscosity of CSM compound decreased,the t10 and t90 were extended,the crosslinking degree decreased,the elongation at break of the vulcanizates increased,the other physical properties and thermal aging property decreased,the oxygen index tended to decrease,and the low temperature resistance was improved.DOS plasticized CSM vulcanizates showed the best low temperature resistance,while chlorinated paraffin plasticized CSM vulcanizates showed the smallest improvement.The CSM vulcanizates with 40 phr DOS met the application requirements in the severe cold conditions.
