Read： 671 Time：17months ago Source：Transform the World with Simplicity

With the development of modern industrial technology, plastics have become a widely used material. From plastic bags, plastic cups, plastic tableware, to auto parts, electronic products, medical equipment, plastic materials play an irreplaceable role.

1. plastic composition

In simple terms, plastic is a polymer compound polymerized from hydrocarbons (I. e. hydrocarbons). Different types of plastics have different physical and chemical properties and application scenarios due to their different compositions and production methods.

common types of plastics are polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polycarbonate (PC), polyamide (PA) and so on. These materials have different characteristics: some have high wear resistance, corrosion resistance, light transmission performance, suitable for electronic products shell, body parts, etc.; some have low temperature resistance, softness, suitable for fresh-keeping bags, diapers and so on.

2. plastic application

In addition to these types of plastics, there are many other types. No matter what kind of plastic, in industrial production and daily life have a wide range of applications.

In the light industry, plastics are often used in the housings and accessories of home appliances, electronics and other products. In heavy industry, plastics are used in automotive, aviation and other fields of parts, structural parts, etc.

In addition, in agriculture, commerce, medical, construction and other industries, plastics also have their own application scenarios. For example, plastic film, planting bags, etc., used in the field of agriculture in the greenhouse, summer and autumn planting and other scenes; plastic water pipes, plastic drainage ditches, etc., are used in municipal construction or landscaping.

3. environmental protection and sustainable development

However, as a widely used material, plastics also bring serious environmental protection and sustainable development problems. The accumulation of plastic waste has become a global problem, which has caused serious harm to the environment and ecology for a long time.

, therefore, in the production, use, treatment and other aspects of plastics, improve environmental awareness, promote the concept of sustainable development, change the existing industrial model, in order to make plastics truly become sustainable materials.

Conclusion

As far as plastic is concerned, we need to see both convenience and environmental issues at the same time. The application of plastics is inevitable, but we can explore better ways to limit it. In the future, more people's attention and efforts will make plastic materials more environmentally friendly and sustainable in the future, and bring greater welfare to mankind.
