As a material widely used in daily life, plastics are not only widely used, but also divided into many different types. However, regardless of the type of plastic has the same main ingredient, which is polymer.

polymers are macromolecular compounds made of many small molecules combined by chemical reactions. This is the basic component of plastic products. Commonly used plastics include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc., all made from different types of polymers.

In addition to polymers, plastics also contain additives, such as color, stabilizers, etc. These additives are designed to change the properties of plastics to make them more suitable for specific applications. For example, polymer materials can be made into white plastic without color, and other colors of plastic can be obtained by adding pigments and colorants.

In addition, plastic has less water absorption and is easy to clean and disinfect, which is one of the reasons for its wide application. However, although plastic has many advantages, it also has many disadvantages, such as environmental pollution and difficult degradation.

In recent years, degradable plastics are gradually coming into people's vision. Unlike traditional plastics, degradable plastics can be decomposed into non-toxic and environmentally friendly materials, so the negative impact on the environment can be reduced. The main components of degradable plastics include polylactic acid (PLA), a multi-polymer.

Of course, the current use of degradable plastics is still relatively limited, and the cost is relatively high. However, with the advancement of technology and industry, this type of plastic is expected to gradually replace traditional plastic in the future and become a more environmentally friendly and sustainable material.

plastic is an indispensable material in our daily life. Its main component is polymer, but it also has problems such as environmental protection and degradation. Over time, we believe that advances in technology and industry will lead to better solutions and more environmentally friendly and sustainable materials.
