Product Detail of Rubber Cushion
Rubber cushion pads are widely used in automobile engines and other mechanical equipment, which have shock absorber, effectively increase the service life of equipment, good sealing performance, wear-resisting and anti-aging properties.
【Product Size】：Customized according to customer needs
【Product Material】：(EPDM/NBR) can also be customized according to the specific use of the product.
【Product Features】：The quality environmental EPDM rubber material has the characteristics of anti-aging, anti-vibration and noise reduction, ozone resistance, high and low-temperature performance.
Automotive rubber mats are characterized by high elasticity and high viscosity. Rubber elasticity is produced by its curl conformation change, rubber intermolecular interactions will hinder movement of the molecular chain, which shows the characteristics of viscous damping, so that the stress and strain are often in a state of imbalance.
The long chain molecular structure of rubber and the weak secondary force between the molecules; The rubber material presents a unique viscoelastic energy, so it has good shock absorption, sound insulation and cushioning performance. Rubber parts are widely used to isolate vibration and absorb shock, because of its hysteresis, damping and the ability to make reversible large deformation. The hysteresis and internal friction characteristics of rubber are usually indicated by the loss factor, the larger the loss factor, the more obvious the damping and the heat of the rubber, the more obvious the damping effect is.
Rubber materials used for shock absorption are generally divided into 5 kinds, namely NR, SBR and BR as ordinary rubber materials. NBR is used for oil resistant vulcanizate; CR for weather resistant rubber; IIR is used for high damping vulcanized rubber; EPR is used for heat-resistant vulcanized rubber. NR, though less dissipation factor, its comprehensive performance is best, excellent flexibility, good fatigue resistance, heat production is low, and the good bonding performance of the metal, cold resistance, electrical insulation and processing performance, thus NR is widely used as shock, resistance to low temperature or weather resistance, but with BR or CR and blending modification.
