High Dispersion Precipitation Method Silica Specification:
Our company's precipitated white carbon black is mainly divided into two categories: rubber grade white carbon black, green tire specific high dispersion white carbon black, and feed grade white carbon black.
High dispersion white carbon black for rubber and green tires
White carbon black for rubber is mainly used in industries such as shoe making, rubber rollers, and tires. Due to its high specific surface area, it has excellent reinforcement performance when applied to rubber products, which can improve the hardness, wear resistance, and tear strength of the products, and extend their service life.
The highly dispersed white carbon black for green tires is a differentiated high-performance product independently developed by our company, which occupies an important position in the domestic and international markets. It can significantly reduce the Rolling resistance of tires and improve the wet skid resistance of tires. It can replace carbon black in a large amount for high-performance tires. While reducing the Rolling resistance of tires, reducing fuel consumption, it can improve the wet skid resistance and steering control safety, and at the same time reduce tire wear, Improved driving safety. Especially in applications such as passenger tyres with low Rolling resistance and winter tyres, its excellent performance is even more obvious. At present, our company produces two major series of silica products for the rubber industry: easily dispersed silica (EDS) and highly dispersed silica (HDS).
Silicon dioxide products were first used in tire applications, mainly for rubber reinforcement. Since these developments in recent decades, although silica remains the key to rubber reinforcement, the latest generation of highly dispersed silica (HDS) is helping to redefine the "magic triangle" of the tire industry.
、
From low surface area materials that improve traction and hysteresis characteristics of winter tires to high surface area materials that improve tread wear and balance Rolling resistance, our company develops new silica materials to meet their specific production and performance requirements.
Silicon dioxide is usually used in combination with silane coupling agents, and practice has shown that tires with added silicon dioxide have the following excellent properties:
Improve wetland traction and fuel efficiency, balance wear resistance
● Enhance the ability to resist cutting, chipping, and tearing
● Promote adhesion to plated steel wire and fabric cords
