Plastic is based on synthetic or natural polymer resins. After adding various additives, it is malleable under certain temperature and pressure, and it can fix its shape after cooling. The process of natural or synthetic polymer resin molecules in the molten state and the uniform distribution of auxiliary molecules around them is called plasticization. It has been reached. This process is called plasticized, but has not yet been reached. It is considered to have not been plasticized.
