What kind of plastic material can support high temperature injection molding?

The performance requirements of the finished product usually need to be considered before selecting injection materials. This includes hardness, durability, heat and chemical resistance, as well as other factors determined by the use and operating environment. Today, we will take stock of the common plastic materials that can support high temperature injection molding?
PPS
PPS is a kind of special engineering plastics with excellent comprehensive properties. It has excellent high temperature resistance, corrosion resistance, radiation resistance, flame retardancy, balanced physical and mechanical properties, excellent dimensional stability and excellent electrical properties. It is widely used as structural polymer materials, and has been successfully applied in the fields of electronics, aerospace, automobile transportation, etc.
PSU
PSU is a kind of linear thermoplastic engineering plastics, which has excellent heat resistance, oxidation resistance, radiation resistance, electrical insulation, outstanding creep resistance and high physical and mechanical properties, excellent chemical corrosion resistance, and is stable to other chemical reagents (such as inorganic acid and alkali salts) except strong solvent, concentrated sulfuric acid and nitric acid.
PEEK
It is a kind of special engineering plastics with excellent performance. Compared with other special engineering plastics, it has more significant advantages, such as high temperature resistance of 260 degrees, excellent mechanical properties, good self lubrication, chemical corrosion resistance, flame retardant, peeling resistance, wear resistance, strong nitric acid, concentrated sulfuric acid, radiation resistance and super mechanical properties, which can be used for high-end mechanical and aviation science and technology products.
PEI
Pei has excellent mechanical properties, electrical insulation, radiation resistance, high and low temperature resistance and wear resistance, and can be transmitted through microwave. Pei also has good flame retardant, chemical resistance and electrical insulation properties. The glass transition temperature is very high, up to 215 ℃. Pei also has low shrinkage and good isotropic mechanical properties. Adding glass fiber, carbon fiber or other fillers can achieve the purpose of reinforcement and modification; it can also form heat-resistant polymer alloy with other engineering plastics, which can be used for a long time under the working temperature of - 160 ~ 180 ℃.
