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