1, high elasticity: low modulus of elasticity, elongation deformation, there can be restored deformation, and can maintain elasticity in a wide range of temperatures ( -50 ~ 150 ° C ).
2, viscoelasticity: rubber materials in the deformation and recovery of deformation by the temperature and time, the performance of the stress relaxation and creep phenomenon, in the vibration or alternating stress, resulting in hysteresis loss.
3, electrical insulation: rubber and plastic - like electrical insulation materials.
4, aging phenomenon: such as metal corrosion, wood decay, rock weathering, rubber will also be due to changes in environmental conditions and aging phenomenon, so that the performance deterioration, life expectancy decline.
5, must be vulcanized to use, except thermoplastic elastomer.
6, must be added to the matching agent. Low specific gravity, low hardness, good flexibility, good airtightness and other characteristics are valuable properties of rubber.
