1. Improvement of rubber properties:
- Improvement of strength and hardness: micro silica powder has high specific surface area and high activity, which can interact with molecules in rubber and increase the cross-linking density between rubber molecules, thus improving the strength and hardness of rubber products and making them more able to withstand external forces.
- Enhancement of abrasion resistance: micro silica powder has high hardness and regular particle shape, which plays the role of filling and enhancement in rubber. These tiny particles can be evenly dispersed in the rubber matrix, effectively resisting friction and abrasion, improving the abrasion resistance and durability of rubber products, and prolonging the service life of rubber products, such as in rubber tires, rubber conveyor belts and other products.
- Enhance aging resistance: micro silica powder can form chemical bonds with polymers in rubber, and can absorb ultraviolet rays and reduce the damage of ultraviolet rays to the molecular chain of rubber, thus slowing down the aging process of rubber products and maintaining the stability of the performance of rubber products.
2. Improve processing performance:
- Micro silica powder can reduce the viscosity and stickiness of rubber, improve the fluidity of rubber, make rubber easier to mold and operate during processing, and improve the processing efficiency and cost-effectiveness of rubber.
