RUBBER STORAGE LIFE FORECAST BASED ON ACCELERATIVE AGING TEST

Based on accelerative aging test,bi-parameter experience kinetic formula was used to simulate the evolutive process of rubber compression set. Unknown variables in experience formula and Arrhenius equation were specified by using linear regression and composite method,reaction velocity was evaluated to extrapolate correlation between compression set and storage time at room temperature. Result is that rubber storage life at room temperature is 2.38 years at 95% of confidence level.
