Fumed Silica, Brand Name : XR, CAS No. : 7631-86-9

We are offering fumed silica.
Other names : silicon dioxide .
　　application
　　1. Rubber-----required to give 40 times the highest strength , modulus, yield point can be increased about 10 -fold , elongation, creep properties can be obtained very significant improvement . Fully meet its reinforcing effect of the level of carbon black and carbon black to overcome the pollution.
　　2. Sealants and adhesives-----thickeners and thixotropic agents can be used to increase the bonding strength, to ensure the free flow of preventing agglomeration and sagging during curing , the collapse of loose , depression, transparency , reinforcement , shear and so on.
　　3. Plastic-----plastic products can be improved density, smoothness and wear resistance. If the surface modification through appropriate , you can achieve the same plastic toughening purposes. In a particular way , can be obtained a high wear resistance, high hardness, polyethylene composite materials.
　　4. Thixotropic polyester resin and gelcoat-----make products plus uniform thickness , shrinkage, while reducing r resin flowing and dripping and reduce resin waste and protect the production environment.
　　5. Putty-----can be used as anti-settling agent , has a good anti-settling effect and excellent thixotropy.
　　6. Paint-----available anti-caking , anti-sagging , emulsification, extinction , suspension, thickening and thixotropic and other functions.
　　7. Fiber-----to protect the fiber surface from water erosion , improved fatigue resistance and aging optical properties.
　　8. Other-----the pharmaceutical industry as a tabletting aid , the active ingredient carrier, efficient pesticide carrier , the semiconductor wafer polishing agents , anti-caking agent powder matter
