Why is silica used in Tyre Rubber?

Silica is commonly used as reinforcement filler in tyre rubber applications for improving tyre performance. Conventional silica grades have poor dispersion in the tyre rubber matrix as silica-silica particle interaction is high while silica-rubber particle interaction is low.

What is precipitated silica used for in tires?

Precipitated silica is a key filler for the tire industry, improving physical and dynamic properties such as tensile strength, abrasion resistance, tear resistance, and wet grip in tires.

What is green precipitated silica used for?

Green precipitated silica from Brisil is used as a reinforcing agent in natural and synthetic rubber and products made from rubbers. It finds applications in belts, conveyer belts, gaskets & seals, rice rollers, and similar applications. The silica particles form physical bonds with the rubber molecule chain to strengthen the vulcanized compound.

Why do tyre rubbers have poor dispersion?

Conventional silica grades have poor dispersion in the tyre rubber matrix as silica-silica particle interaction is high while silica-rubber particle interaction is low. This leads to uneven concentrations of silica in the rubber matrix impacting physical properties.

What are the benefits of silica in tires?

Precipitated silica in tires improves physical and dynamic properties such as tensile strength, abrasion resistance, and tear resistance. It is also perceived by the tire industry as a material which can address the environmental challenges associated with tire production and can replace carbon black in tires.

What are the advantages of precipitated silica?

Precipitated silica offers several advantages, particularly in the context of Paints, Coatings, and Inks. Its smaller particle size results in higher flow ability, which improves the anti-settling properties of these products. Additionally, precipitated silica's oil absorption properties prevent spreading ability, which is beneficial in various industries including Rubber, Tyres, Footwear, and Food Products.
