Engineering Thermoplastics
Thermoplastic polymers are a type of plastic that softens upon heating to elevated temperatures and hardens upon cooling. Thermoplastic polymers may be amorphous or semi-crystalline, with differences in mechanical performance, chemical resistance, and service temperature capability. AETs represent a specialized family of high-performance thermoplastics with exceptional properties, including short- and long-term thermal stability, enhanced mechanical performance, excellent chemical resistance, superior wear properties, and good fire performance thermal properties. Compared to low-performance commodity plastics, AETs provide numerous advantages over metallic materials, including lower density for weight reduction, good vibration damping characteristics, electrical or thermal insulation, chemical and corrosion resistance, increased design freedom, and fatigue resistance. Some of the more common high-performance AETs used by Greene Tweed include: Polyaryletherketone (PEEK, PEK, PEKK): The polyaryletherketone family of resins includes various combinations of ketonic and ether linkages. The members of this high-performance family include PEEK (polyetheretherketon e), PEK (polyetheretherketon e), and PEKK (polyetherketoneketo ne). These are all semi-crystalline engineering polymers, with outstanding high-temperature performance, harsh chemical resistance, good toughness, and excellent mechanical strength and dimensional stability. Polytetrafluoroethyl ene (PTFE) is a fluoropolymer engineering thermoplastic that has exceptional friction/wear properties in addition to outstanding chemical resistance and electrical insulation performance.
