Transparent powder is a kind of non-metallic mineral, high transparency, good whiteness, non-toxic and tasteless, acid and corrosion resistance. With high transparency, the refractive index of the filling material itself is very close to the refractive index of the vast majority of synthetic resins, so the amount of filling does not affect the transparency of the finished product; It can improve the surface smoothness and wear and scratch resistance of the product. With low oil absorption and large filling capacity, the transparent powder provided by our company is made of the high purity and whiteness of the sodium sulfate powder.

◆ High transparency: the refractive index of the filling material itself is very close to the refractive index of the vast majority of synthetic resins, so the filling amount of the filler does not affect the transparency of the finished product;
◆ High hardness: can improve the product surface smoothness and wear resistance and scratch resistance;
◆ Low oil absorption: to reduce the manufacturing cost of products;
◆ Easy to disperse: it has good wetting property, good adsorption performance and easy to disperse for various resins;
◆ Strong stability: with excellent weather resistance and excellent corrosion resistance.
Specifications: 800-3000 mesh;
Packing: 25kg fiber woven bag;
Note: "Highly moisture-proof products".

Scope of application:
Transparent master material, rubber and plastic, coating industry (transparent paint, PE, PO transparent primer) stearate, hyaluronic acid, transparent silica gel, transparent glass glue and other industries.

Application suggestions:
High grade transparent primer, the amount of 10-20% can be added.
Transparent powder is added to the primer, because it increases the hardness and toughness of the paint film, the grinding ability may have a slight impact.
In the process of production feeding, input should be slow and small during the operation of the mixer, otherwise its dispersion may be affected.
