Ultrafine nano silica
Widely used in high temperature room temperature silicone rubber,liquid silicone rubber,adhesive-free glue,paint,coating,ink,resin,adhesive,rubber and plastic film,color masterbatch,cable material,resin fiberglass products,composite materials,electronic products,cosmetics,pharmaceutical products and other fields.
1.It plays the role of transparency,reinforcement,wear resistance,high temperature resistance,tear resistance and dielectric property in high temperature room temperature silicone rubber products.
2,in the paint,paint,ink products to thicken,thixotropic,extinction,dispersion,anti-settling,anti-caking,anti-sagging,improve stability,water content adjustment,optimize the role of free flow and static applications.
3,in the adhesive products to strengthen,thicken,thixotropic,anti-precipitation,anti-caking,processing aids,improve stability,adhesion and other effects.
4.It plays the role of anti-sagging,anti-aging,anti-impact,high strength and smooth and delicate surface in resin glass fiber reinforced plastic products and composite materials.
5,in the plastic film products to play the role of anti-aging,anti-impact,prevent foaming polyester cracking,improve strength and transparency.
