WebSep 3, 2015 · Compression set, sometimes called C-set, is an indicator of how a material behaves under certain conditions. The compression set test for foams and sponges include a 50% compression at various temperatures. Room temperature 23°C, intermediate 70°C, and high (100°C for silicone). Since heat is an “accelerator” of compression set, an ...

HNBR has excellent abrasion, compression set, tensile, and tear properties. Unlike standard nitriles, HNBR resists ozone, sunlight, and other atmospheric environments. Natural Rubber / Isoprene has excellent dynamic properties.
WebCompression set. The most important property of rubber subject to compression loads is the modulus of elasticity. For soft rubber it varies between 1 and 10 MPa, while for hard rubber it is around 1000MPa. The modulus of elasticity depends on the temperature of the rubber, the time that the rubber has been at the test temperature, the degree of ...
