Welcome to inquire more details.

Used in the new rubber materials (silicone rubber, etc.), can make its dispersion leveling excellent, tear resistance, tensile resistance, anti-aging and has a reinforcing effect. Compared with the middle or low grade silica get by end precipitated on the market, quartz powder is superior to precipitated silica in SiO2 content (above 99.6%), moisture content (less than 0.1%), particle size, oil absorption and other major technical indexes.

(1)It can improve the strength of silicone rubber and product quality (filling volume 30-70%);It is an indispensable filler for ultraviolet radiation, infrared reflection and high dielectric insulation.

(2)When filling more than 20% of ultra-fine silica in the  large size truck tire and high-speed radial car tire,  the tire will has good anti-skid, heat dissipation, wear resistance and other characteristics. Due to the addition of ultra-fine quartz powder can significantly reduce the rolling resistance of the tire, enhance the tear resistance and cutting resistance and strength, keep the tire ice resistance and skid resistance, this was known as green tire.

(3)When superfine silicon powder is added into other tires and rubber products, its elasticity, toughness, wear resistance and strength are obviously better than those of tires and rubber products filled with conventional and ordinary silicon dioxide.

(4)Ultrafine quartz powder is filled in natural rubber, butadiene rubber, butadiene rubber and other rubber materials. The powder is easy to disperse, the mixing process performance is good, the calendering and pressing property is good, and it can improve the vulcanization speed of vulcanized rubber, improve the rubber viscosity, and replace 50% white carbon black filling in the rubber material.It has no obvious influence on the mechanical properties of the products (tensile strength, constant extension strength, elongation at breaking, permanent deformation at breaking, tearing strength and hardness of the products), but it can greatly reduce the cost of the products, especially suitable for rubber products such as cots, rubber hoses, wire and cable and its sheath.
