A brief introduction
SS/CS/AS series amorphous silica since it put into the market it has been receive a wide range of recognition by our customer. Owing to its excellent application performance it can be compare with either the Grace¡¯s products in United States or Degussa¡¯s in German. In order to meet different demands our product separate into two different types. One type of product its surface has been through organic treatment and its series number is marked with L. These types of product mainly apply for paint industry. The other has not been through organic treatment this type of product mainly served as anti-block aid.

Applications
The Amorphous Silica appears as white free flowing powder. It is highly efficient anti-blocking aid for plastic films. It also provides slip improvement. Due to its high purity and low hardness its abrasiveness is negligible. It¡¯s no sedimentation easy adding and well-dispersed features make this product enjoy the application fields like:
¡ñ Food packing films
¡ñ Furniture coatings
¡ñ Decorative paint
¡ñ Other general industrial coatings

Packing
All of our product is supplied in 10kg/Bag and 14 bags / pallet.

Storage
The Amorphous Silica Materials of SS/CS/AS420B, SS/CS/AS420Z, SS/CS/AS520, SS/CS/AS530 and SS/CS/AS/540, is not covered by the organic on the particle surface, so they have the liability of sedimentation when reserving. It is suggested that it should be mixed together with the fine powder wax or take other anti-sedimentation measure.

The SS/CS/AS420L, SS/CS/AS520L, SS/CS/AS530L and SS/CS/AS540L, is covered by the organic on the particle surface. They have optimal suspension, no hard sedimentation through long-time reserving. The film has bulginess, well abrasion resistance and anti-scratch.
