Plastic Raw Materials

Posted by: chinaeye 2021-10-17 Comments Off on Plastic Raw Materials

We need a variety of plastics in the mold production process. According to the scope of application of plastic raw materials, it can be divided into general plastics, engineering plastics, special plastics.


Common plastics are: PP, PVC, PE, PS, etc .

Common engineering plastics are: ABS, PC, PMMA, POM, PA6, PA66, PET, PBT, SAN, etc .;

Common types of special plastics are: PPS, PEI, etc .


Engineering plastic particles are often modified by some general-purpose plastics; such as changing some of the internal molecular structure and adding other ingredients such as glass fiber.


Engineering plastics are industrial plastics that are used as industrial parts or shell materials. They have excellent strength, impact resistance, heat resistance, hardness, and aging resistance.

Features include:


a. Thermal properties: high glass transition temperature (Tg) and melting point (Tm), high heat distortion temperature (HDT), high long-term use temperature (UL-746B), large use temperature range, and small thermal expansion coefficient.


b. Mechanical properties: high strength, high mechanical modulus, low latent change, wear resistance, fatigue resistance.


c. Others: chemical resistance, excellent electrical resistance, flame resistance, weather resistance, and good dimensional stability.


Sino Mould is a manufacturer of plastic molds with deep research on plastic raw materials.

If you have any plastic product projects, we can also help you set up a plastic product production line-Custom Design Injection Molding Line Set Up.
