Engineering polymers, or engineering plastics, are a kind of thermoplastic materials with some premium properties or functionalities that commodity plastics do not have. Here are some common types of engineering plastics, PBT, PC, PET, POM, and PPE.

Although commodity plastics are materials which have a wide variety of uses, it may not meet the requirements of highly demanding applications. As a result, engineering plastic can be a viable option. Compared to commodity plastics, engineering plastics are more able to cope with challenging environmental conditions. Under such conditions, they perform well in many properties, such as mechanical strength, dimension stability, heat resistant, chemical resistance, and so on. It can also substitute metal or wood materials in many cases which is more weight-saving and cost-effective. Hence, they are frequently applied in more demanding industries like automotive, aerospace, medicine, electronics, military…
