Plastics are macromolecules polymerized by addition polymerization or polycondensation reaction with monomers as raw materials. Their deformation resistance is medium, between fiber and rubber. They are composed of synthetic resin, fillers, plasticizers, stabilizers, lubricants, pigments and other additives.

Composition introduction

The plastic we usually use is not a single component. It is made of many materials. Among them, high polymer (or synthetic resin) is the main component of plastics. In addition, to improve the performance of plastics, it is necessary to add various auxiliary materials to high polymer compounds, such as fillers, plasticizers, lubricants, stabilizers, colorants and antistatic agents, to become plastics with good performance.

Synthetic resin

Synthetic resin is the main component of plastics, and its content in plastics is generally 40% ~ 100%


Fillers, also known as fillers, can improve the strength and heat resistance of plastics and reduce costs. For example, adding wood powder to phenolic resin can greatly reduce the cost, make phenolic plastic one of the cheapest plastics, and significantly improve mechanical strength.


Plasticizer, or plasticizer, can increase the plasticity and softness of plastics, reduce brittleness and make plastics easy to process and shape.


Stabilizer mainly refers to the reagent that keeps the stability of polymer plastics, rubber and synthetic fibers and prevents their decomposition and aging.

Colorants can make plastics have various bright and beautiful colors. Organic dyes and inorganic pigments are commonly used as colorants.


The function of a lubricant is to prevent the plastic from sticking to the metal mold during molding, and make the plastic surface smooth and beautiful. Common lubricants include stearic acid and calcium magnesium salts.


Prevent the plastic from yellowing and cracking due to thermal oxidation during heating forming or high-temperature use.

Antistatic agent

Plastic is a poor conductor of electricity, so it is easy to carry static electricity, and antistatic agents can give plastic light to medium conductivity, to prevent the accumulation of static charge on products.


Remove impurities and caking.
