Plastic is a common material, we can see it in all kinds of daily necessities. But few people really understand the composition of plastic and how it affects the environment. Below we will introduce the composition of plastic in detail to help you better understand this material. Classification
of

1. plastics
plastics are divided into petroleum, natural and synthetic categories according to the source of materials. Petroleum refers to those extracted from petroleum, including polypropylene, polyethylene, etc. Natural refers to those made of natural materials, such as rubber and natural cellulose. Synthetic category refers to artificial synthesis, including polyurethane, polyamide, etc.

2. the composition of plastic

plastic is the main component of polymer compounds. Polymer compounds are long-chain molecules composed of many molecular units, in which the monomers are usually chemical monomers, such as ethylene, styrene and propylene.

In addition to polymer compounds, plastics also need additives and filling materials. The additives are typically chemical additives such as stabilizers, dyes and light stabilizers, etc. Filling materials can increase the hardness and strength of the plastic. Commonly used filling materials include ceramics, silicates, and bleaching powder.

3. the impact of plastics on the environment

plastics, as a common material, brings a lot of convenience, but it also brings a lot of environmental problems. The production of plastics requires a large amount of energy, resulting in increased energy consumption. Plastic in the cutting process will produce a lot of waste, disposal and landfill of these wastes will cause environmental pollution. Plastic also affects biodiversity and deforestation.

Recently, with the increasing awareness of environmental protection, people began to look for more environmentally friendly alternatives, such as degradable plastics and environmentally friendly plastics. These new types of plastics are gradually developing and will become an important trend in the plastics industry in the future.

plastic is a common material with a wide range of uses, its composition and environmental impact also require our attention. Only through continuous innovation and improvement can the goal of sustainable development be achieved.
