1. Add an anti-yellowing paste double 2,5 vulcanizing agent to the
Silicone Daily Necessities, which contains a high amount of hydrogen silicone oil, which promotes the obvious improvement of the anti-yellowing effect of the silica gel, improves the transparency of the silica gel, and prevents the vulcanizing agent from splashing;
2. The organic surfactant is added to the white carbon black to control the size of the secondary particles, and under the action of the compound anti-yellow agent, the yellowing degree of the silica gel can be effectively controlled;
3. Add an anti-yellowing agent called pyrophosphoric acid to enhance the anti-yellowing ability of the rubber compound without reducing the physical and mechanical properties of the rubber compound.
