Filling masterbatch refers to the mixing and kneading of various additives, fillers and a small amount of carrier resin during the plastic processing and molding process, and the granules and powders obtained are called masterbatch.
The masterbatch is composed of carrier resin, filler and various additives. The limit of additives or the content of fillers in the masterbatch is several to ten times higher than the actual amount required in plastic products. During the molding process, the ratio of the masterbatch and 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 in the actual product. Masterbatch can usually be divided into ordinary filler masterbatch (referred to as filler masterbatch) and functional masterbatch, such as color masterbatch, anti-fogging masterbatch, etc. The main component of filler masterbatch is filler, which is mainly used for the processing and molding of polyolefin (polyethylene and polypropylene), also known as polyolefin filler masterbatch.
Filling masterbatch Application field
The filling masterbatch can be used to process plastic film, garbage bags, shopping bags, vest bags, packaging bags, etc. It has good dispersion, no white spots and black spots on the blown film, high fineness, and guarantees the gloss and toughness of the product. It is mainly suitable for filling and modifying woven bags, packing belts, hollow products, pipes, sheets, injection molded products and plastic fast food boxes, which can improve the performance of plastic products and reduce product costs.
Filling masterbatch use Instructions:
Directly mix the filler masterbatch and the damp plastic raw material evenly, and then the product can be processed and produced.
Used in the production of blow molding and wire drawing, the addition ratio is 1.0~3.0%
Used in sheet and injection molding production, the addition ratio is 2.~5%
The specific addition ratio can be determined by the user according to the damp condition of the plastic.
