Characteristics:

1) White dispersed powder

2) Can be dissolved by NaOH and HF, but cannot be dissolved by other kinds

    of acid, water and solvents

3) It has a good performance

4) With resistance to higher temperature

5) Will not combust and has good isolation

Applications:

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
