The world around us is surrounded by plastic. Many goods and objects that we use on a daily basis, from computers to refrigerators, are all made of plastic. However, not all plastics are made of the same materials, they can use different plastic materials and Composition, which are called compounds, each of which has unique properties. Compounds are used to improve the properties of a product. Basically, a compound is a homogeneous mixture of different materials that are combined to create a new material with desirable properties .Compounds can be composed of two or more substances. In general, compounds consist of three main components, which include compatibility agent, polymeric base and other additives. When we add additives such as softeners, fillers, stabilizers, etc. to the polymer base, we turn it into a compound. Basically, these additives are added to improve the properties of the polymer, and the important thing is that there must be compatibility between the product and the compound. If they are not compatible with each other, they cannot be distributed continuously and uniformly in polymer materials, and as a result, they reduce their quality. There are different types of compounds and they are used in a wide range in the industry, the application of each one can be different according to the type and characteristics of each. In this article, we are going to check the applications of compounds in industries and get acquainted with its types. Follow us to the end of the article for more information.
