The products for rubber, plastic and paint industries have been approved by ISO-9002. Its Certificate Number is 2100/20019955.
Items: SK, CY and NA, Intensely improved the quality of filler. Having made repeated tests, we have successfully produced the subjected products that are suitable for rubber, plastic and paint industries according to the standard of the technical stipulations required by rubber, plastic and paint professions.
Usage: A series products of Item Sk are used in chemical industry, item CY, in plastic and rubber industries, item NA, in paint and hydro-paint purposes.

Characteristics:
    1. Chemical grade of Item SK can go up the steady of product appearance, prevent the expansion and contraction of the products in the course of the procession, increase the flow of the plastic and burden controlled.
    2. Being a stratified texture, Talc is basically flake or scale form.
    3. The particle of talc is arranged in a row according to the flowing direction of the materials in the course of grinding. Being flake form on the whole, the scattered flakes are joined together based on the principle of the minimum resistance. Therefore, it can strength the rigid of the filler and anti-deformed on the high temperature. In the course of producing plastic products, talc can improve the physics of the products, strength the tensile, shearing, anti-bending, pressure, hardness, anti-deformed, anti-extending rate, coefficient of expansion. In virtue of such kinds of advantage, talc powders are regarded as reinforced filler.
    4. Items SK & CY have a function of anti-oxidizer, to prevent the products from being heated, being broken by sun-light or oxidization, being reduced strength or brittleness in the polymer. In actual, such kinds of the phenomenon often happen in the course of producing polyethylene and plastic lines, such as PVC, EVA, TPR, PE, ABS as well as various kinds of rubber products.
    5. A series products of hydro-paint grade have the characters of good-covering rate, high-whiteness, harmonious particle size, and good-dispersing. A series products of oiled paint have the characters of good-transparent, good-harmonious particle size, low-oil absorption etc., mainly used in fluorescent paint, reflex-light paint, carbon fluoride paint, polyurethane-hydro-paint, emulsion paint with good healthy etc.
    6. A series products of coating grade have the suspension of the products improved. Being regarded as an anti-precipitating agent, the coagulations have the coating paint thicken further, have the thickness controlled, have the flow controlled, have the color harmonized, have the coating products dried and anti-watered, have the chemical reaction and adhesion prevented.
