With its unique high elasticity, rubber has an irreplaceable position in the field of materials. At present, rubber materials have been widely used in various fields of cutting-edge technology, national defense construction and national economy. With the development of modern engineering technology, the demand for rubber in various industries is also increasing, and higher requirements are set for the performance of rubber. Single materials can no longer meet many performance requirements, and must be modified. At present, the modification of rubber materials has become an indispensable technical means for scientific research, technical development and actual production of sealing strip manufacturers. The main purpose of rubber modification is to improve its physical and mechanical properties, or to make rubber have some special properties, such as thermal conductivity, electrical conductivity, photolithography, light storage, magnetic properties, electromagnetic wave shielding and absorption, sound imitation, sound insulation, and noise resistance. Abrasion, cold resistance, corrosion resistance, radiation resistance, oil resistance, solvent resistance, heat aging resistance, oxidation resistance, light aging resistance, ultraviolet resistance, antibacterial, antistatic, vibration resistance, air tightness, medical resistance, water absorption, and super high strength , High damping, low hysteresis, memory shape, etc.
