Rubber heat aging test

Our company conducts "rubber thermal aging tests" that help evaluate the properties of materials in actual usage environments.
Using a method compliant with JIS K6257 (Method for determining thermal aging characteristics of vulcanized rubber and thermoplastic rubber), rubber test pieces are suspended in a gear oven to produce specimens with varying heat treatment times.
Additionally, tensile tests are performed on heated natural rubber (NR) to investigate changes in mechanical properties, while hardness is measured simultaneously. Changes in the properties of the rubber are also examined, confirming that rubber elasticity is lost and the material becomes harder with heating.
