Processing Properties of Standard Chinese Rubber Stored for 30 Years
The structure and processing properties of standard Chinese rubber naturally stored for more than 30 years were analyzed using FTIR,Mooney viscosity determination,and rubber processing analyzer and the mechanical properties of vulcanizate before and after aging were also determined.The molecular crosslinkage and degradation of standard Chinese rubber after long-term storage lead to the increase in Mooney viscosity and gel content and decrease in processing properties and mechanical properties before and after aging.
