Super engineering plastics

Among engineering plastics, this resin has high mechanical strength, heat resistance (150°C or higher), and chemical resistance. It is utilized for industrial products used in even harsher environments than engineering plastics.

【Main materials handled】
・PSF (polysulfone)
Capable of adapting to a wide range of temperatures from -100°C to 175°C, and possessing excellent hydrolysis resistance, it is also resistant to water. It is widely used as a separation membrane material for medical and food filters.

・PEEK (polyether etherketone)
A high-performance resin among super engineering plastics, with a continuous use temperature of 250°C and features such as heat resistance, chemical resistance, and radiation resistance. It comes in multiple grades, including glass fiber reinforced.

・PAI (polyamide-imide)　
It has heat resistance, durability, and minimal linear expansion. While it is flame retardant and has a wide range of operating temperatures, it also has the property of expanding due to water or moisture.

・PES (polyethersulfone)
A translucent amber-colored super engineering plastic with ultra-high heat resistance and non-crystalline structure. It is flame retardant and possesses heat resistance, chemical resistance, resistance to hydrolysis, and electrical properties.

・PPS (polyphenylene sulfide)
The continuous use temperature is 240°C. It has high tensile strength and rigidity over a wide temperature range, and has excellent dimensional stability.

・PTFE (polytetrafluoroethylene)
It is a type of Teflon resin that has chemical resistance that does not cause chemical reactions with other substances due to the strong bonding force of carbon and fluorine. It has the best electrical insulating properties among resins. It has good sliding properties but is vulnerable to scratches.

・PCTFE (polychlorotrifluoroethylene)
It is a fluoropolymer with excellent gas barrier properties, and in particular, water vapor properties are the lowest among plastics. It has the lowest friction properties of any substance.

・PEI (polyetherimide)
It retains high strength at high temperatures and has excellent electrical properties. The wear resistance is not very good, and it is easy to cause chipping and burrs during the cutting process.

・PVDF (Polyvinylidene fluoride monopolymer)
It has the highest dielectric constant among fluoropolymers and has excellent mechanical properties. It is used in many fields such as welding tanks and parts because of its high heat resistance temperature, superior chemical resistance, and conformity to the Food Sanitation Law.

・PFA (tetrafluoroethylene perfluorovinyl ether copolymer)
It can maintain mechanical strength in a wide range of minus 200°C to 260°C and can be used stably. It is a resin developed for injection molding by reducing the melt viscosity of PTFE, and has higher hardness than PTFE, is resistant to scratches, and has dimensional stability than PTFE.

・ECTFE (tetrafluoroethylene-ethylene copolymer)
Although it is very processable, it is not a perfluoropolymer, so its chemical resistance is slightly lower than that of perfluorinated polymers such as PFA.

・FEP (tetrafluoroethylene hexafluoropropylene copolymer)
Melting point is 265-275°C and has excellent mold-releasing properties at low temperatures.

・PI (polyimide)
Thermosetting resin utilized as components in extremely stringent specifications environments due to its high heat resistance of up to 500°C, high strength, resistance to plasma, and radiation characteristics.
