Silica has a wide range of uses, and different products have different uses. Used as a good reinforcing agent for synthetic rubber, its reinforcing performance is second only to carbon black, and even better than carbon black after ultra-fine and proper surface treatment.
To
Silica is added to the resin to improve the moisture-proof and insulating properties of the resin. Filling in plastic products can increase slip resistance and oil resistance. Filled with silicone resin, it can be made into plastic with resistance above 200℃.
To
Silica can be used as a filler in polyethylene, polypropylene, polybutene, epoxy resin and other plastics, which can improve the elastic strength and wear resistance of the plastic, as well as the thermal stability of hardness. Silica used in cables can also improve the electrical insulation of cables. For example, methyl vinyl silicone rubber high-voltage wires need to use fumed silica or high-quality precipitated silica. It is often difficult to separate the two layers of plastic film, and the bag opening is difficult to open when bagging, so silica is a very popular opening agent.

In the production of rubber shoes, people not only require fastness to rubber shoes, rain boots, sports shoes, travel shoes, fitness shoes, ballet shoes, etc., but also require beautiful colors, comfort and lightness. Silica not only has good reinforcement, abrasion resistance, slip resistance and upper adhesion, but also a good light-colored reinforcement material. Therefore, it plays an important role in the development of rubber shoes to provide the quality and style of shoes. Important role.
To
Silica is used in adhesives made of natural rubber or synthetic rubber to provide thixotropy and reinforcement. At the same time, it can also improve adhesion due to its stretchability, which is high in quality and low in price. Silica can also be used in some products to improve free flow, such as grass fertilizers, fungicides, laundry bleach, phenol and urea plastic products, rubber sulphur and anti-caking mixtures.
