General purpose plastics have the advantages of good formability and low price, but its disadvantages, such as easy aging and deformation, bring a lot of inconvenience to use. In order to overcome these shortcomings, it can be improved by modifying and adding additives to meet the needs of its practical application. The application of Barium Sulphate in general plastics is one of the research hotspots in recent years.
