Precipitated Silica

Characteristics: 1) White dispersed powder 2) Can be dissolved by NaOH and HF, but cannot be dissolved by other kindsof acid, water and solvents3) It has a good performance 4) With resistance to higher temperature 5) Will not combust and has good isolationApplications: 1) Shoes-making industry: rubber outsole reinforcement agent similar to blackcarbon. It brings the light color and transparent appearance of rubber outsolewith excellent performance 2) Tyre industry: decreases friction on ground sharply, and increases the tyreholding on the wet and icy ground. The bonding between curtain threads orwoven 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 andresistance to water 5) Coating industry: it provides the performance in preventing coating fromaggregating and hanging down. It can increase the viscosity and dull thecoating shine 6) Pharmaceutical industry: it gives a function of increasing the viscosity, floatingand dispersing. It can be a carrier and an anti-lumping agent
