Explanation

Generally speaking, general purpose plastics refer to plastics with large output, wide use, good formability and relatively low price. general purpose plastics usually include five varieties, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile butadiene styrene co polymer (ABS). The specific characteristics and applications of various general purpose plastics are as follows: polyethylene (PE): common polyethylene can be divided into low density polyethylene (LDPE), high density polyethylene (HDPE) and linear low density polyethylene (LLDPE). polyethylene is mainly used in various packaging film, tube, injection molding, hollow blow molding products and other fields. Polypropylene: polypropylene has more varieties, mainly homopoly polypropylene, block copolymerized polypropylene and random copolymer polypropylene. homopolymer polypropylene is mainly used in wire drawing, fiber, injection molding, BOPP film and other fields, while copolymer polypropylene is mainly used in home appliance parts and other fields. polyvinyl chloride (PVC): due to its low cost and self extinguishing characteristics, polyvinyl chloride is widely used in the construction field to manufacture sewer tube, plastic steel doors and windows, plates, artificial leather and other products. polystyrene (PS): polystyrene is widely used as transparent raw material, and its application fields include automobile lampshade, transparent cup, container, etc. ABS: With excellent physical, mechanical, and thermal properties, it is widely used in household appliances, instrument casings, accessories, and other fields, especially in the field of household appliances, with a very large amount of usage. These kinds of general purpose plastics play an important role in different fields and meet the needs of various products.
