2. Low density: only 67% of the normal EPDM seals.
3. Good aging resistance: the service life under normal conditions is not less than 15 years.
4. The hardness changes little with temperature: the temperature can reach -60°C to +130°C, and the hardness changes within the range of -20°C to +40°C. The hardness changes are not higher than 5HA, which is better than traditional PVC and ordinary EPDM.
