Product Description

Silica is the raw material for manufacturing glass, quartz glass, water glass, optical fiber, important components of electronic industry, optical instruments, handicrafts and refractories, and is an important material for scientific research. Silica can also be used as a lubricant and is an excellent flow promoter, mainly as a lubricant, anti-sticking agent and flow aid.Precipitated silica with special physic-chemical properties, work as reinforcing transparent fillers highly valued in formulation of rubber-based blends. In particular, They lead to enhanced tensile strength, tear strength and abrasion resistance and increase hardness of vulcanized rubbers. On the other hand, They reduce consumption of rubbers and therefore reduce the cost.

1) Shoes-making industry: rubber outsole reinforcement agent similar to black carbon. It brings the light color and transparent appearance of rubber outsole with excellent performance

2) Tyre industry: decreases friction on ground sharply, and increases the tyre holding on the wet and icy ground. The bonding between curtain threads or woven material and rubber compound is improved

3) Silicon rubber: its aging, resilience and compression set are increased

4) Plastic industry: increases the plastic products' flexibility, strength and resistance to water

5) Coating industry: it provides the performance in preventing coating from aggregating and hanging down. It can increase the viscosity and dull the coating shine

6) Pharmaceutical industry: it gives a function of increasing the viscosity, floating and dispersing. It can be a carrier and an anti-lumping agent
7) For Light-colored, color and High-grade transparent rubber products. 
For PE, PP, powder products as filler with good fluidity property.

As food additives, feed additives, Pesticide carrier with good fluidity and anti-caking property.

For glass cement, sealant, painting, coating, printing ink, as thickener and Anti precipitating agent.
