The properties and uses
of general plastics in the field of raw materials for chemical production
Abstract

This paper introduces in detail the properties and uses of general plastics in the field of raw materials for chemical production. Through the discussion of the nature, production process, use and market situation of common general-purpose plastics such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, ABS resin and polymethyl methacrylate, readers can have a more comprehensive understanding of general-purpose plastics.

1. Introduction

general-purpose plastics have a wide range of applications in the field of chemical production raw materials, and have attracted much attention due to their unique properties and uses. This article will discuss the common general plastics in detail.

2. the nature and use of general plastics

1. polyethylene (PE)

polyethylene is a colorless and transparent thermoplastic, has good low temperature resistance, good chemical stability, can resist most of the acid and alkali erosion, but not heat. Polyethylene is commonly used in the production of films, pipes, containers, wire and cable.

2. Polypropylene (PP)

Polypropylene is a semi-crystalline thermoplastic with high strength, hardness and heat resistance. Polypropylene is widely used in home appliances, automobiles, construction, packaging and other fields.

3. Polyvinyl chloride (PVC)

Polyvinyl chloride is a colorless and transparent thermoplastic with good acid and alkali corrosion resistance and high electrical insulation. PVC is commonly used in the production of pipes, profiles, wire and cable, packaging materials, etc.

4. Polystyrene (PS)

Polystyrene is a transparent thermoplastic with excellent electrical insulation properties and acid and alkali corrosion resistance. Polystyrene is commonly used in the production of household appliances, instrumentation, toys, tableware and so on.

5. ABS resin

ABS resin is a kind of thermoplastic with excellent comprehensive properties, with high strength, good toughness, easy processing and so on. ABS resin is widely used in home appliances, automobiles, construction, toys and other fields.

6. Polymethyl Methacrylate (PMMA)

Polymethyl Methacrylate is a transparent organic glass with high transparency, excellent weather resistance, electrical insulation and processing properties. Polymethyl methacrylate is commonly used in the production of lamps, billboards, display stands, building materials, etc.

3. production process and market situation

general plastic production process mainly includes polymerization, granulation, molding and other steps. With the continuous development of science and technology, the production process of general plastics is also constantly improving and optimizing, improving production efficiency and quality.

in the market, the demand for general plastics is large, and the price is relatively stable. With the improvement of environmental awareness and the promotion of sustainable development strategies, some new environmentally friendly general-purpose plastics have gradually emerged, bringing new choices to the market.

4. conclusion

general-purpose plastics have a wide range of applications in the field of chemical production raw materials, and different types of general-purpose plastics have unique properties and uses. With the continuous progress of science and technology and the changing market demand, the production process and market situation of general plastics are also constantly developing and changing.
