Manufacturing Methods
of Engineering Plastics
1. Introduction

Engineering plastics have a wide range of applications in the field of chemical production raw materials. Due to their excellent properties, such as high strength, light weight, and corrosion resistance, they are widely used in aviation, Automotive, electronics, construction and other industries. This article will detail the manufacturing methods of engineering plastics, including polymerization, blending, reinforcement and other processes.

1. polymerization process

polymerization process is the core technology of engineering plastics manufacturing, through the polymerization reaction of monomer molecules connected into polymer chains. Common polymerization methods include bulk polymerization, solution polymerization, suspension polymerization and emulsion polymerization. When selecting a polymerization method, it is necessary to consider factors such as monomer properties, product requirements, and production conditions.

2. Blending process
The
blending process is to mix two or more polymers in a certain ratio to improve certain properties of engineering plastics. The compatibility, interfacial force and other factors should be considered in the blending process to ensure the stability of the blend system.

3. Reinforcement process

reinforcement process is to improve the mechanical properties of engineering plastics by adding reinforcement materials, such as glass fiber, carbon fiber, etc. In the reinforcement process, the dispersion of the reinforcement material and the interfacial force with the matrix should be considered.
