Silica 975GR is a high specific surface area precipitated white carbon black. It is mainly characterized by high reinforcing strength, high wear resistance, and low rolling resistance. It has a higher performance level than 955GR and is mainly used in high-end green tires and high-performance rubber parts. It is made from high-quality sodium silicate as the raw material, through precise precipitation, modification treatment, and ultra-fine grinding. It is a fine white powder with an advanced pore structure, excellent compatibility with rubber and silane coupling agents, and can significantly improve the mechanical properties of rubber products.

FAQ
Q: How to choose between 975GR and 955GR?
A: 975GR offers stronger reinforcement and better wear resistance, making it suitable for high-end tires and high-performance products; 955GR has a higher cost-performance ratio and is used for regular rubber parts.
Q: Which scenarios are mainly applicable to?
A: Green tires, high-performance shoe soles, conveyor belts, precision seals, silicone products, etc.
Q: Storage precautions?
A: Store it sealed in a dry and ventilated environment, avoiding moisture absorption and clumping, and keeping away from humid environments.
