What is a masterbatch?

Color masterbatch = pigment + carrier + auxiliary agent. Generally speaking, the carrier is a thermoplastic resin, which has good wetting and dispersing effects on the pigment, and has good compatibility. The production methods of masterbatch include ink method, washing method, kneading method and metal soap method. Color masterbatches are classified according to different carrier resins: PE masterbatch, PP masterbatch, ABS masterbatch, PVC masterbatch, EVA masterbatch, etc. According to different uses, it can be divided into injection masterbatch, blow molding masterbatch, spinning masterbatch, etc. The advantages of color masterbatch are: make the pigment have better dispersibility in the product; help maintain the chemical stability of the pigment; ensure the stability of the product color; protect the health of the operator; keep the environment clean; easy to use. Disadvantages are: poor predictability of the coloring effect; affecting the strength of plastic products, plastics are easy to bend and deform; high cost, general-purpose masterbatches often use high-heat-resistant grade pigments, resulting in waste.

 

What is injection molding?

Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression method and die-casting method. The injection machine uses plastic molding molds to make thermoplastics or thermosetting materials into various shapes of plastic products. Injection molding is realized by injection molding machines and molds. Plastic products are widely used in aerospace, automotive, home appliances, construction and other fields because of their light weight, high specific strength, good chemical resistance, and easy processing and molding.

 

Application of aluminum paste in masterbatch and injection molding

The advantages of aluminum silver paste applied to the color masterbatch and injection molding industry are no dust pollution, many varieties, and low price; the disadvantage is that it is not easy to disperse in the plastic, pollutes the workshop environment, affects the health of workers, and affects the mechanical properties of the plastic. Mainly used in low-grade plastic products such as plastic oil drums, mulching film, plastic pipes, plastic shoe soles, wire sheaths and convenient bags.

 

Application of aluminum pigment powder in masterbatch and injection molding

The advantages of aluminum pigment powder applied to the color masterbatch and injection molding industry are easy to disperse in plastics, no solvent pollution, and low price. Compared with aluminum paste, it is solvent-free, environmentally friendly and safe; the disadvantage is that it is easy to cause dust pollution and pollute the workshop. The environment affects the health of workers. Due to the dry ball milling, the thickness of the aluminum sheet is uneven, and the particle size distribution is wide. Most of the products are used in low-grade plastic products. Mainly used in low-grade plastic products such as plastic oil drums, mulching film, plastic pipes, plastic shoe soles, wire sheaths and convenient bags.

 

Application of aluminum granules in masterbatch and injection molding

The advantages of aluminum granules applied to the color masterbatch and injection molding industry are easy to disperse in plastics, no solvent pollution, no dust pollution, automatic weighing, easy mixing, low odor, excellent storage stability, and strong versatility. Particle size distribution Narrow, the thickness of the aluminum sheet is relatively uniform, environmentally friendly, and safe; the disadvantage is that the production process is complicated and the cost is high. Mainly used in household appliances, panels, face masks, beverage bottles and their caps, daily necessities, toys, helmets, safety helmets, luggage, car bumpers, auto parts and mobile phone cases and other higher-end or environmentally-friendly products.
