Smart Redesign With Peek Keeps Neutron Source Cool
, in consultation with its distributor AIN Plastics, a division of ThyssenKrupp, developed a one-part jacket that replaced PC with extruded Tecapeek. The polyetheretherketone (PEEK) raw material comes from Victrex plc, Thornton Cleveleys, Lancashire, U. K. American Industrial Plastics (AIP),. Daytona

Plastics that perform
of high-performance plastics includes the following base materials: ECTFE (ethylene-ETFE (ethylene-tetrafluoroethylene) chlorotrifluoroethylene). FEP (fluorinated ethylene propylene). LCP (liquid-crystal polymer). PAI (polyamide-imide). PCTFE (polymonochloro-PEEK (polyetherether ketone) trifluoroethylene). PEI

Plastic Nuts become a hot topic
but can be injection molded using special equipment. Another engineering plastic called PEEK ( polyetheretherketone) has mechanical properties resembling those of polyamide-imide. PEEK has a deflection temperature of nearly 400°F and can be blended with PTFE. Unlike polyamides, PEEK is injection
