CAS No. | 7631-86-9 |
Molecular Formula: | O2Si |
EINECS | 231-545-4 |
Molecular Weight: | 60.08 |
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
Appearance: White power or granular form, It can be dissolved by NaOH,HF.
