Summary of Types and Characteristics of Super Engineering Plastics [Minoru Sangyo Co., Ltd.]

Super engineering plastics, referred to as "super engineering plastics," are a general term for engineering plastics that are particularly excellent in heat resistance and chemical resistance among engineering plastics.

Similar to engineering plastics, there is no clear definition for super engineering plastics, but their characteristic is that they have heat resistance of approximately 150°C or higher and can be used for long periods in high-temperature environments. Some super engineering plastics can even be used at temperatures above 260°C. Additionally, many super engineering plastics contain fluorine, which gives them high resistance to solvents and chemicals. Super engineering plastics that can be used in even higher temperature environments are not only applicable in areas where engineering plastics are used, but it is also noted that their molecular chains contain benzene rings. On the other hand, fluorine resins do not contain benzene rings, but they have the highest electronegativity, and the bond between carbon and fluorine is very stable, which gives them excellent heat resistance, cold resistance, and other properties, making them one of the super engineering plastics. For medical devices, they are adopted due to their high transparency and ability to withstand high temperatures from steam sterilization. However, while super engineering plastics are high-performance resins, they also come with a high cost. Nevertheless, the characteristics and cost advantages of super engineering plastics often outweigh the costs, leading to their active consideration.
