Antioxidants | Thermal Protection for Plastics | amfine.com

Plastics are susceptible to oxidative degradation during high temperature melt processing operations and end use, as well as during long-term storage. Oxidation is a chain reaction process involving free radical and hydroperoxide intermediates. Antioxidants inhibit this process by reacting with and decomposing these reactive species.

Polymer stabilizers - Wikipedia

Polymer stabilizers (British: polymer stabilisers) are chemical additives which may be added to polymeric materials, such as plastics, to inhibit or retard their degradation. Common polymer degradation processes include oxidation, UV-damage, thermal degradation, ozonolysis, combinations thereof such as photo-oxidation, as well as reactions with catalyst residues, dyes, or impurities.

Processing Plastic: The various methods. Injection Molding ...

The main method used for processing plastic is injection molding. With this process, the plastic is placed into a hopper. The hopper then feeds the plastic into a heated injection unit, where it is pushed through a long chamber with a reciprocating screw. Here, it is softened to a fluid state. A nozzle is located at the end of the chamber.
