In addition to measuring the normal physical properties according to the following immersion liquids (
A immersion test (25°C, 24 hours) was conducted in a mixture of chlorofluorocarbon refrigerants or refrigeration oil, and changes in hardness and volume were measured.After the immersion test, the rubber sheet was placed in an oven at 150°C. After heating for 1 hour, the external appearance was observed to see if foaming occurred.
