Information

Fillers are inert substances added to plastics, mainly in order to reduce costs or improve performance.
The positive effect of the filler is to improve the heat resistance, hardness, dimensional stability, creep resistance, flame retardant, smoke elimination and degradability of the product, reduce the shrinkage rate of the molding to improve the accuracy of the product; The side effects have led to product performance decline or even a substantial decline, the most obvious decline in the performance of impact strength, tensile strength, processing fluidity, transparency and product surface gloss.

Therefore, the selection of plastic filler should refer to the following principles:
1, the filler does not react with the resin and additives, and the ability to absorb the plasticizer is small.
2, the amount of filler should be appropriate, does not affect the resin properties and does not reduce the mechanical properties of products, can not make products cracking phenomenon.
3, The filler has the appropriate fineness, can be evenly distributed in the resin, does not contain crystallizing water.
4, The filler should have good heat resistance, it can not promote the decomposition of resin, under high temperature,it do not change color and decompose.
5, The filler should have acid resistance, alkali resistance, insoluble in water, oil and all solvents.
The commonly used fillers for color masterbatch are calcium carbonate, barium sulfate and talc powder. Glass microbeads are a kind of new material with wide applications and excellent properties developed in recent years, which deserves attention.
In addition to the filler, colorant is also an indispensable component of the masterbatch formula, its significance has far beyond the original purpose of beautifying products. Plastic coloring is to give plastic products many characteristics and functions, it greatly enhances the original commercial value of products, who can reflect the distinctive characteristics in color outside the development of a unique field of application can occupy the commanding heights in the fierce competition in the market.
The organic pigments for plastics produced by Yuhong pigment have bright color, good dispersion, high color concentration, good migration resistance, heat resistance and other properties. The company is equipped with advanced testing equipment at home and abroad, and the product quality is guaranteed. Yuhong pigment people take customer as the center, continuous improvement, continuous innovation, conscientious service to every customer.
