Excellent reinforcing properties: Silica has a high specific surface area and high activity, which allows it to exert excellent reinforcing effects in rubber and other materials. Especially in the rubber industry, the use of silica as a reinforcing agent accounts for 80%-90% of the total output. It can be widely used in rubber soles, tires, rubber hoses, tapes, rubber rollers, rubber sealing tubes and other products. Its reinforcing effect can significantly improve the mechanical strength and tear resistance index of the product.

Improve physical properties: Silica has excellent properties such as porosity, high dispersion, light weight, good chemical stability, high temperature resistance, non-combustibility and good electrical insulation. These characteristics make materials filled with silica significantly improved in terms of high temperature resistance, wear resistance, and weather resistance.

Improve processing performance: During the processing of rubber and other materials, silica can improve its fluidity and reduce viscosity, thereby improving processing performance. At the same time, silica can also improve the printing effect and enhance the rheology control of thermoplastics, making the processing process smoother.

Environmentally friendly and safe: Silica is white, non-toxic, tasteless, non-flammable, and has good insulation, so it will not pollute the environment or harm human health during use.

In summary, silica, as a filler in the preparation of rubber, plastics and other materials, has significant advantages in reinforcing, improving physical properties, improving processing performance, and being environmentally friendly and safe, so it has been widely used.
