Polyamideimide PAI (also known as TORLON) is also a thermosetting plastic with a long-term operating temperature of 250 ° C and excellent low temperature resistance. TORLON also has excellent wear resistance and impact resistance.
Polyetheretherketone PEEK, long-term working temperature up to 160 ° C, short-term working temperature up to 260 ° C, enhanced grades with better high temperature performance.
Polyetherimide PEI, long-term working temperature up to 170 ° C, short-term working temperature up to 200 ° C.
The long-term working temperature of polyphenylene sulfide PPS can reach 220 °C, and the short-term working temperature can reach 260 °C.
Polyvinylidene fluoride PVDF has a long-term working temperature of 150 ° C and a short-term working temperature of up to 160. It also has excellent corrosion resistance and high mechanical strength and rigidity.
Polytetrafluoroethylene PTFE has a long-term working temperature of 260 ° C and a short-term working temperature of 280 ° C. It has excellent corrosion resistance and is commonly known as "Plastic King". It also has an extremely low coefficient of friction.
Polysulfone PSU has a long-term operating temperature of 150 ° C and a short-term working temperature of 180 ° C. Polysulfone PSU also has good comprehensive electrical properties. PES performance is similar to PSU, with higher operating temperature, long-term operating temperature of 180 ° C, short-term 220 ° C.
Nylon 46, with a long-term operating temperature of 135 ° C, has excellent toughness and good chemical resistance.
The above is a brief introduction to several commonly used high-temperature plastics. Selecting a plastic, only one operating temperature parameter is not enough, but also consider the material's corrosion resistance, wear resistance, and price.
