Plastics are also called synthetic resins, mainly because the most important application of synthetic resins is to make plastics. In order to facilitate processing and improve performance, additives are often added, and sometimes they are directly used for processing and forming, so they are often synonymous with plastics. The content of synthetic resin in plastics is generally 40~100%. Due to the large content, and the properties of resins often determine the properties of plastics, people often regard resin as a synonym for plastics. For example, confuse polyvinyl chloride resin with polyvinyl chloride plastic, phenolic resin and phenolic plastic. In fact, resin and plastic are two different concepts. Resin is a kind of unprocessed raw polymers, it not only used to make plastics, and coatings, adhesives and synthetic fiber materials. Except for a very small part of plastics containing 100% resin, the vast majority of plastics need to add other substances in addition to the main component resin.
Synthetic resin is also the basic raw material for the manufacture of synthetic fibers, coatings, adhesives, insulating materials, etc. The widely used resin concrete also uses synthetic resin as the cementitious material. Because synthetic resin has obvious performance and cost advantages compared with other competitive materials, its application penetrates into all aspects of the national economy. Packaging is the largest market for synthetic resins, followed by construction supplies. Electronics, electrical and automobiles are also important application areas for synthetic resins. Other markets include furniture, toys, entertainment, household appliances, and medical supplies.
