- a 3 mm X 2 mm X 20 mm bridge is used as a sample, and after measuring the weight and specific gravity of this sample, a stainless steel tube having a capacity of 4 m1 is measured.
- the inside of the pressure vessel was heated to 288 ° C, held for 1668 hours, returned to room temperature, measured the sample's weight and specific gravity, and steamed. Calculate the weight change (%) and volume change (%) before and after the treatment.
- a new crosslinked rubber molded article having excellent chemical resistance, excellent mechanical strength, heat resistance, and especially improved heat resistance at high temperatures is provided. It is possible to provide a bridging elastomer composition and a bridging agent.
