What are five general purpose plastics?
People call general purpose plastics some varieties of plastics with great performance, low price, wide application and wide influence. General purpose plastics There are five main types of general purpose plastics, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and ABS. They are all thermoplastics.
Polyethylene (PE) is most productive grade in plastics industry. According to density, polyethylene can be divided into: low density polyethylene LDPE, high density polyethylene HDPE, linear low density polyethylene LLDPE.
Polyethylene
Polypropylene (PP) is a thermoplastic produced by polymerization of propylene. Polypropylene is widely used due to its low price, good overall performance and ease of processing. Especially in recent years, rapid development of polypropylene resin modification technology has made it widely used.
Polypropylene
Polyvinyl chloride (PVC) is a plastic obtained by polymerizing vinyl chloride. By adding plasticizers, its hardness can be significantly changed. It has a wide range of applications from hard foods to soft foods.
polyvinyl chloride
Polystyrene (PS) can be divided into general purpose polystyrene (GPPS), high impact polystyrene (HIPS) and expandable polystyrene (EPS).
Polystyrene
ABS is a terpolymer of acrylonitrile (A), butadiene (B), and styrene (C). The relative content of three monomers can be arbitrarily changed to obtain different resins.
ABS
General plastic prices
We mentioned above that general purpose plastics are divided into polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and ABS, and price of each plastic is different. individually. And region is not same, market is not same. Particularly in recycling industry, due to different use values of plastics, general purpose plastics will be subdivided and then varieties with highest profit will be found. So what is price of regular plastic? Pay attention to platforms like Qia Xun and you can check daily market price of common plastics in waste plastics price market. What's more, if you are interested in this industry and want to enter recycling industry, especially if you want to find plastic recycling manufacturers, you can also find upstream and downstream supply chains on this platform.
