General-purpose polymers, also known as general-purpose plastics or commodity plastics, are the most widely used materials among the thermoplastic resins in the world. General-purpose plastics are thermoplastics that are produced in extremely high volume for applications that do not really require exceptional properties.
Most of the plastic products are made from 6 major types of commodity plastics, ABS, PE, PMMA, PP, PS, and PVC. General-purpose polymers are usually the result of styrene monomer polymerization. They are easy to process and very cost-effective. And because of these two reasons, it has a wide variety of applications, like packaging, cutlery, food containers, electrical & electronics, toys, daily necessities, household products, and medical device, etc.
