Study on additives of plastic pigments

The additives of plastic pigments play a vital role in the production process of plastic products. After years of research and practice, people gradually understand the effects of different kinds of additives on the properties of plastic pigments. This article will describe in detail the common additives of plastic pigments and discuss their application in the product process.

Part One: Anti-stick agent

Anti-adhesive is a common plastic pigment additive, which can effectively reduce the viscosity of plastic pigments in the process of processing and improve the fluidity of products. The use of anti-adhesive can reduce the melting temperature of plastic pigments during injection molding, thus saving energy and improving production efficiency. Anti-stick agent can also improve the surface finish and transparency of plastic products, improve the quality of products. The common anti-adhesive agents are stearate esters and polyethylenic acid esters.

Part Two: Plasticizer

Plasticizer is another commonly used plastic pigment additive, which can increase the flexibility and ductility of plastic pigments. Plasticizer plays a lubricating role in the manufacture of plastic products, can improve the fluidity of plastic pigments, reduce the processing temperature and energy consumption. Plasticizer can also improve the cold resistance, heat resistance and weather resistance of plastic products, and extend the service life of the product. Common plasticizers include phthalates and epoxy lipids.

Part Three: Stabilizer

Stabilizer is an important additive to protect the properties of plastic pigments, which can prevent the oxidation, degradation and discoloration of plastic pigments during processing and use. The use of stabilizers can improve the heat resistance and light resistance of plastic pigments, prevent product aging and deterioration, and extend its service life. The common stabilizers are organotin compounds, organoantimony compounds and phenols.

Part Four: Colorants

Colorant is an additive used to adjust the color of plastic pigments, which can give rich color to plastic products. The use of colorants can meet the needs of different customers, adding beauty and artistic sense to the product. Common colorants are organic pigments, inorganic pigments and metal pigments.

The additive research of plastic pigments involves many aspects, such as anti-adhesive, plasticizer, stabilizer and colorant. Different kinds of additives can give different properties and characteristics of plastic pigments, to meet the requirements of the product on fluidity, flexibility, resistance and so on. Through the reasonable application of additives, the production efficiency and quality of plastic products can be improved, providing strong support for industrial development.
