Precipitated Silica dioxide Rubber Filler For Medchine CAS

Filling Agent , Precipitated Silica , White Powder , Used In Tires And Coatings​.

Recommendations and Applications:

Because of lots of advantages, silica is widely used in many industries.

For rubber industry, silica acts as reinforcing agent to produce colored rubber product

to replace carbon black, or to produce transparent & semi-transparent products.

It also has features like strong adhesive, tear resistance and hot aging resistance,

so it is used to replace carbon black also in black products, to produce high quality tires,

such as off-road tires, engineering tires and radial tires.

Apart from as reinforcing agent, silica is also used in medical, pesticide, ink, paint, coating,

toothpaste, paper, food, animal feed, cosmetic, storage battery and other industries.
