Principle of thermoplastic cycle

The molding process of thermoplastic materials theoretically involves only physical processes such as phase transition, just like how ice turns into water when heated and water turns back into ice when cooled. Therefore, this type of plastic should be easily reusable, such as waste materials from injection molding (sprues, runners, etc.). However, during the molding process, slight chemical changes such as oxidative degradation and thermal degradation often occur, which may result in the performance of second-generation recycled plastics being different from the new plastics used for the first time!

Polymer plastics are divided into Thermoset thermosetting plastics and Thermoplastic thermoplastic plastics.
Thermoplastic thermoplastics vary depending on the conformation or morphology of the polymer chains:
Amorphous thermoplastic: such as: ABS,PC,PS,PVC,PAN, PMMA,PEI, PPO，SAN, AES,AS, ASA...
(Semi -) Crystalline thermoplastic: such as: PPS,PE, PP, PBT, PET,Nylon(PA), POM,PEEK...
Liquid crystal polymers (LCPs) are liquid crystal thermoplastic plastics.
