Effect of rubber plasticizer:
1. Reduce the force between rubber molecules.
2. Improve the processing performance.
3. Improve the physical and mechanical properties of rubber materials.
4. Cost reduction
The growth principle of rubber plasticizer.
Non-polar plasticizer plasticizing non-polar rubber (dilution)
Polarity plasticizer growth of polar rubber (melting)
Requirements for rubber plasticizers.
1. Good growth rate, low consumption and fast absorption.
2. Good compatibility with rubber, small volatility and no migration.
3. Good cold resistance, water resistance, oil resistance and solvent.
4. Good electrical insulation and good flame resistance.
5. Non-toxic, colorless, odorless, cheap and easy to use.
A rubber plasticizer is a reagent.
Plasticizing rubber refers to add certain substances to the rubber, can make the rubber intermolecular force is reduced, thus reduce the glass transition temperature of rubber, rubber plasticity, liquidity, easy rolling, extruding and forming operation, at the same time also can improve some of the physical and mechanical properties of vulcanized rubber, such as lower hardness and stress, endowed with higher flexibility and lower heat production, improve the cold resistance, etc.
