Material processing, also known as plastic molding processing, is a general term for various processes for converting synthetic resins or plastics into plastic products, and is a large production department in the plastics industry. Using ethylene as the main raw material, propylene, 1-butene and hexene are copolymers. Under the action of the catalyst, the obtained polymer is flashed, separated, dried, granulated, etc. by slurry polymerization or gas phase polymerization. In the process, a finished product having uniform particles is obtained. These include, for example, sheet extrusion, film extrusion, tube or profile extrusion, blow molding, injection molding, and rotational molding.
