Synthetic materials, also known as man-made materials, are materials artificially processed by chemical methods or polymerization of different substances. They mainly refer to the synthesis of macromolecular polymers from small molecular organic substances such as olefins through chemical synthesis. Many things people use now are organic synthetic materials, such as many glasses are made of plexiglass, of course, the windows and tires on cars are, plastic bags used in life, chassis on induction cookers, etc. It can be said that organic synthetic materials have been able to replace the high temperature resistant functions of some metals in many aspects!

Synthetic materials include plastics, fibers, synthetic rubber, adhesives, and coatings. Synthetic fibers and artificial fibers are collectively referred to as chemical fibers. Synthetic plastics, synthetic fibers, and synthetic rubber are known as the three major organic synthetic materials in the 20th century. Its appearance has greatly improved the living standards of the people, and its importance to the national economy and people's livelihood is self-evident.

Material classification

The three major synthetic materials are designated plastics, synthetic rubber, and synthetic fibers. They are high molecular compounds synthesized from low molecular compounds by artificial methods, also called polymers, with a relative molecular weight of more than 10,000. Natural polymers include starch, cellulose, natural rubber, and protein. The three major synthetic materials are artificially synthesized polymers. Synthetic materials are increasingly replacing metals and becoming important materials used in modern society.
