Main ingredients: calcium carbonate, PE, auxiliary

 

Features:

Masterbatch refers to the process of plastic processing and molding. For the convenience of operation, the required various auxiliaries, fillers and a small amount of carrier resin are first mixed and kneaded, and then measured, mixed, melted and extruded through equipment such as extruders. Pellets obtained through processing such as , pelletizing and other processes. The auxiliary limit or filler content in the masterbatch is several to ten times higher than the amount required in actual plastic products. During the molding process, the ratio of the masterbatch to the matrix resin must be adjusted according to the content of the relevant components in the masterbatch and the amount that needs to be added to the actual product.

This product of our company is made of calcium carbonate plus PE carrier and auxiliary. It has the advantages of large filling capacity, superior processing performance, good color and gloss of the product, and can be well soluble with the matrix resin and significantly improve the processing performance of the resin. and performance, and can greatly reduce production costs. It is an ideal multi-functional modified masterbatch. This product introduces special functional groups, so it can improve the interface bonding between polyolefin plastics and non-polar objects, thereby improving the adhesion and compatibility with other objects. At the same time, the product itself has excellent water resistance, chemical corrosion resistance and light resistance, does not cause harmful chemical reactions with other plastic auxiliaries, and does not contain impurities harmful to resin processing. The products are suitable for the production of various polyethylene products, including injection molding, pipes, blow molding, sheets, blister molding, woven bags, garbage bags, colored strips, PE cloth, plastic mesh, blown film, cast film, etc.
