Applications and Properties
The physical properties of K80 make it an all-purpose matting agent
Packing and storage
Packaged in multiple layer Kraft paper, 10kg per bag
They are inert and extremely stable chemically. However, due to their high specific surface area, they can absorb moisture and volatile organic compounds from the surrounding atmosphere. Therefore, we recommend to store the products in sealed containers in a dry, cool place, and removed from volatile organic substances. Even if a product is stored under these conditions, after a longer period it can still pick up ambient moisture over time, which could lead to its exceeding the specified moisture content. For this reason, our recommended use-by date is 24 months after date of manufacture. Product more than 24 months old should be tested for moisture content before use in order to make certain that it is still suitable for the intended application.
Silica Dioxide （TM325）
CAS:7631-86-9 White powder
It is the superfine precipitated silica made by special processing technology. It has excellent reinforcing and dispersing properties. it can completely or partially replace the Fumed silica and greatly reduce the production cost of customers.
It is applicable to strengthen the tire, rubber shoes and other products, improve the product"s flexural resistance, crack resistance and physical performance.
Good abrasive resistance, high strength and transparent properties are available, Prolong the use effect of the product
Application ： Mechanical rubber goods. Light colored and translucent
soles, micro cellular plates and TPR

Easy to absorb water, after the use of the part, must tighten the bag to isolate water vapor.
After contact with human skin, local discomfort will be caused, and gloves should be worn and cleaned in time.
Shelf life: two years
Silica Dioxide （TM365 TM518 TM360）
CAS:7631-86-9 White powder
It used in High transparent and reinforced silicone rubber. It is stronger than ordinary precipitated white carbon black.
Especially in the silicon rubber industry, it not only makes the product have good tensile strength and wear resistance, but also makes the product transparent, good color and appearance

Silica Dioxide
（Silica Matting agent TM300）
CAS:7631-86-9
White powder
TM300 Matting agent powder is a special silicon dioxide precipitate made by gel process. It reduce gloss in coatings when solvents evaporate reducing the film thickness, this allows its particles to form a micro rug on the surface of the dried film, that disperses light rays reflecting on the surface.
Good matting efficiency and Good dispersion.
Application：paints, coatings, and ink
