Silica 115GR is a low specific surface area precipitated white carbon black. Unlike 955GR and 975GR which have high reinforcing properties, it focuses on high fluidity and easy processing. It is specially designed for conventional rubber products and scenarios with low reinforcing requirements. It is made from high-quality silicate as the raw material, through gentle precipitation, drying and granulation processes. It is a white, loose powder without any odor, with excellent fluidity, and does not easily form lumps. It has good compatibility with various rubbers and does not require complex dispersion processes. It is suitable for batch production scenarios such as ordinary tires, rubber accessories, and seals.

Product advantages
The core advantage is excellent fluidity. During mixing, no additional dispersants are required. It quickly blends into the rubber compound, does not agglomerate or form lumps, significantly improving processing efficiency; the low specific surface area design is suitable for low reinforcement requirements, without artificially increasing the rubber hardness and retaining the toughness of the product; the low oil absorption value can reduce the amount of rubber compound, lowering production costs; the pH value is moderate, not affecting the stability of rubber vulcanization, and is not prone to frosting or cracking problems; the impurity content is low, with wide compatibility, suitable for natural rubber and synthetic rubber, and suitable for batch production of conventional rubber products.

FAQ
Q: What are the core differences between 115GR and 955GR, 975GR?
A: 115GR has a lower surface area and better fluidity, focusing on ease of processing and low reinforcement, making it suitable for conventional products; the latter two have higher surface areas and emphasize high reinforcement and high wear resistance.
Q: What products are they mainly used for?
A: Ordinary tires, rubber accessories, sealing rings, rubber tubes, low-end shoe materials, and other conventional rubber products.
Q: What are the storage and usage precautions?
A: Store in a sealed, dry and ventilated place to prevent moisture and caking; the addition amount is generally 5% - 15%, and can be adjusted according to the product requirements.
