In the field of injection molding, plastics that can maintain stable performance for long periods in environments above 150\u00b0C are generally defined as high-temperature materials.<\/p>\n\n\n\n
High-Temperature Plastics Categories<\/p>\n\n\n\n
Polyether Ether Ketone (PEEK)
Long-term service temperature: \u2264 250\u2013260\u00b0C
Melting point: \u2248 343\u00b0C
One of the highest-performance specialty engineering plastics, offering exceptional strength, wear resistance, and self-lubricating properties. It is an ideal metal replacement material. Widely used in aerospace, medical implants, and automotive engine components.<\/p>\n\n\n\n
Polyimide (PI)
Long-term service temperature: \u2264 250\u2013300\u00b0C
Thermal decomposition temperature: > 500\u00b0C
Recognized as the polymer with the best high-temperature performance. It remains stable under extreme conditions. Due to its extremely high melting point, it is very difficult to injection mold and is mainly used in cutting-edge fields such as aerospace and nuclear energy.<\/p>\n\n\n\n
Polyamide-Imide (PAI)
Long-term service temperature: \u2264 260\u2013275\u00b0C
Melting point: \u2248 305\u00b0C
Maintains extremely high strength and rigidity at elevated temperatures, with excellent wear resistance. Ideal for precision mechanical parts such as bearings, seals, and gears operating under high load and high-temperature conditions.<\/p>\n\n\n\n
Liquid Crystal Polymer (LCP)
Long-term service temperature: \u2264 240\u2013300\u00b0C
Melting point: \u2248 280\u2013300\u00b0C
Excellent flowability and dimensional stability due to its unique molecular structure. Commonly used in miniaturized, thin-wall precision electronic components, such as RF connectors.<\/p>\n\n\n\n
Polyphenylene Sulfide (PPS)
Long-term service temperature: \u2264 200\u2013240\u00b0C
Melting point: \u2248 285\u00b0C
Outstanding chemical resistance and flame retardancy, combined with high rigidity and excellent dimensional stability. One of the most widely used specialty engineering plastics in the automotive and electrical & electronics industries.<\/p>\n\n\n\n
Perfluoroalkoxy (PFA)
Long-term service temperature: \u2264 260\u00b0C
Melting point: \u2248 305\u00b0C
A fluoropolymer with extremely strong chemical resistance, capable of withstanding almost all chemicals. Suitable for ultra-pure chemical delivery systems and semiconductor manufacturing equipment in extreme environments.<\/p>\n\n\n\n
Polyetherimide (PEI)
Long-term service temperature: \u2264 170\u2013180\u00b0C (Heat deflection temperature up to 200\u00b0C)
Combines excellent heat resistance, dimensional stability, and mechanical strength. It is inherently flame retardant with low smoke generation. Transparent grades are available. Commonly used in medical applications, electronic housings, and devices requiring high-temperature sterilization.
Polyphenylsulfone (PPSU)
Long-term service temperature: \u2264 180\u2013207\u00b0C
Excellent impact resistance and hydrolysis resistance. Can withstand repeated steam sterilization. Frequently used in medical surgical instrument trays and baby bottles where safety and durability are critical.<\/p>\n\n\n\n
Polysulfone (PSU)
Long-term service temperature: \u2264 170\u2013180\u00b0C
Good transparency and resistance to steam and hot water hydrolysis. A common material for medical equipment and food-contact containers.<\/p>\n\n\n\n
High-Temperature Nylon (PPA \/ PA4,6)
Long-term service temperature: \u2264 160\u2013220\u00b0C
Melting point: \u2248 295\u2013325\u00b0C
High-temperature nylon achieved through molecular modification. Features low water absorption and excellent oil resistance. Suitable for automotive engine components that come into contact with lubricants and fuels at high temperatures.<\/p>\n\n\n\n
Polyether Ketone Ketone (PEKK)
Long-term service temperature: > 260\u00b0C
Belongs to the same polyaryletherketone (PAEK) family as PEEK. Similar performance profile and can be used as a cost-effective or performance-specific alternative to PEEK in certain applications.<\/p>\n","protected":false},"excerpt":{"rendered":"
