Rubber plasticizer refers to industrial supplies that can reduce the force between rubber molecules, thereby reducing the glass transition temperature of rubber. It refers to industrial supplies that can reduce the force between rubber molecules, thereby reducing the glass transition temperature of rubber. Make the rubber plasticity, fluidity, easy to roll, press out and other forming operations, but also improve some physical and mechanical properties of vulcanized rubber, such as reducing hardness and fixed elongation stress, giving higher elasticity and lower heat generation, improve cold resistance.
