White masterbatch refers to the masterbatch made of high-quality pigment + high-quality resin + additives, which is refined through high-speed mixing and twin-screw production. It is suitable for sheets, blown films, pipes, injection molding, blow molding, blister molding, and other products.

Main text

Masterbatch refers to a plastic colorant made of a high proportion of pigments or additives and thermoplastic resins, which are well dispersed. The selected resin has good wetting and dispersing effects on the colorant and has good compatibility with the colored material. That is: pigment + carrier + additive = masterbatch. Masterbatch coloring is the most commonly used plastic coloring method today. Masterbatch is a new product for coloring plastics and fibers developed in the 1960s. It is a polymer compound obtained by uniformly attaching pigments in excess amounts to resins. Although this question is simple, there are many possibilities, specifically: 1. The masterbatch has not been carefully tested, and the pigment is too little or too much. 2. The measurement is inaccurate during use. There are a lot of Chinese companies, especially small and medium-sized enterprises, that measure arbitrarily. 3. There are problems with the matching of the masterbatch and the resin. This may be due to improper selection of the carrier of the masterbatch, or the manufacturer may change the resin variety at will. 4. The machine temperature is improper, especially high, and the masterbatch stays in the machine for too long, causing the color powder to burn.

2. Application fields

Injection molding, blow molding, wire drawing, cast film, extrusion, blown film, foaming, sheet, pipe, granulation, hollow, EVA, blown bottle, sheet, household appliances, toys, packaging materials, wires and cables, plastic bags, automobiles, building materials, sports and leisure products, packaging bags, packaging bottles and other plastic products industries. Applicable plastic raw materials PE, PO, PP, ABS, PVC, etc.

3. Technical indicators

Titanium dioxide content: 20%-80% (depending on the customer).

Four. Product Features

White masterbatch has the advantages of bright color, bright colors, high tinting strength, good dispersibility, high concentration, good whiteness, strong hiding power, reasonable price, good migration resistance and heat resistance. It ensures product quality and yield, reduces energy consumption and improves production efficiency. It is the characteristic of a new generation of economical white masterbatch. Stable quality, complete specifications, preferential prices and timely delivery. Special color matching and proofing can be made according to customer needs, and small samples can be provided.

Five. Use ratio and storage and transportation

It depends on the whiteness requirements of the product. Users can also mix it according to the color requirements of the product.

White masterbatch is stored and transported as non-dangerous goods in a ventilated and dry warehouse.
