What Are The Functions Of Plasticizers In Rubber Products
Plasticizers are widely used in rubber products because of their good effects, low dosage, fast absorption speed, good compatibility with rubber, and low volatility. Then you know that plasticizers are used in rubber products. What does it do?
From different perspectives, there are many types of plasticizers in rubber products. However, the same plasticizers used in rubber products have roughly the same effect. The specific plasticizing effects are as follows, we can take a look.
1. The role in rubber processing. The plasticization of rubber means that the addition of certain substances to the rubber can reduce the force between the rubber molecules, thereby reducing the glass transition temperature of the rubber, making the rubber plastic and fluid, facilitating the molding operations such as rolling and extruding, and improving the rubber Processing technology improves the pass rate and dimensional stability of rubber products, reduces energy consumption, and improves mixing efficiency.
2. The role of rubber mastication and mixing. Improve certain physical and mechanical properties of vulcanizates, such as reducing hardness and tensile stress, imparting higher elasticity and lower heat generation, improving cold resistance, etc., and also improving the resistance to reversion and heat resistance of vulcanizates It has both internal and external lubrication and dispersion functions, and can be used in the plasticizing and mixing process of natural rubber and synthetic rubber.
3. The role in rubber mixing. It can promote the dispersion of fillers and other additives, shorten the mixing cycle, reduce mixing energy consumption, and reduce rubber heat generation. Used in rubber processing, it can improve the extrusion performance of rubber, increase the extrusion speed and the smoothness of semi-finished products.
