Injection molding is a method of producing shapes for industrial products. Injection molding can also be divided into injection molding compression method and die casting method. Injection molding is a method of producing shapes for industrial products. Injection molding can also be divided into injection molding compression method and die casting method. Plastic injection molding is a method of plastic products. The molten plastic is injected into the plastic product mold by pressure, and then cooled and molded to obtain various plastic parts. The most commonly used plastic is polystyrene.

Brightening masterbatch is also known as fluorescent brightener masterbatch. The whitening masterbatch produced with imported fluorescent whitening agent, covering agent, antireflection nucleating agent and other substances. The whitening masterbatch has the functions of whitening, brightening, and removing yellow-green light.

The fluorescent whitening agent can absorb the invisible ultraviolet light in the light and emit visible blue light. After being superimposed with the yellow light emitted by the fabric, it complements the formation of white light, which increases the white light emitted by the fabric, and the naked eye can feel that the white fabric has become obviously Brightening.

Fluorescent brightener is non-irritating to the skin and has no adverse effect on wound healing. Fluorescent brightener CBS is water-soluble and can be completely excreted quickly and completely through normal metabolism. Fluorescent brightener CBS is not teratogenic. Not carcinogenic. CBS is highly degradable and has no effect on the biological chain.

The defoaming masterbatch is a functional masterbatch developed to solve the moisture problem in recycled plastics. It can greatly absorb the moisture of the plastic during the molding process, and solve the problems of blistering, cracks, spots, etc.
