What are the common additives in plastic products?
The main function of plastic additives is to improve the performance of plastic products, increase production efficiency and reduce production costs. In the production process of plastic products, the function of plastic additives is becoming more and more important. At present, the common plastic additives in plastic molding process are:
1. Foaming agent
A plastic foaming agent is an organic compound that can vaporize low-molecular organic compounds at a specific temperature, such as difluoromethane.
2. Flame retardant material
Flame retardant material can improve the flame resistance of plastic products. The injection-molded products with the flame retardant property will slow down the fire burning. The flame-retardant material includes aluminum, halide, phosphate, etc.
3. Lubricant
Lubricant is a kind of additive that can improve the demolding process of plastic products in the injection molding process and can improve the surface finish of the products. Paraffin wax, synthetic wax is the most common in the injection molding industry.
4. Reinforcement materials
In the production of plastic products, reinforcement materials occupy a large proportion of the raw material. The purpose of adding reinforcement material is to increase the strength and rigidity of plastic products. The most common reinforcement materials are glass fiber, asbestos, silica, etc.
