Industries & Professions /
More than 13,000 companies are involved in the plastics industry in the United States. It is a very broad industry, but it can be divided into three primary divisions: resin suppliers, suppliers of other materials, and compounders (companies that prepare plastic formulations). These three divisions send their materials to processors, which then sell products to other industries that use them. The major markets for plastic and plastic parts are the automotive, electronics, computers, telecommunications, and packaging industries. These industries use plastic pieces or parts in their products.
