What is Plastic Annealing Richfields Corporation
· Below is a simple illustration of how the three stages of plastic annealing take place First the finished plastic product is placed inside a heating chamber or an oven that s supplied with a constant amount of heat. The temperature may depend on the type of plastic since not all polymers have the same values for the glass transition temperature.
