A. We need a screw that is usable at 200C in air only, so no chemical resistance needed. I like the high strength of the Carbon Fiber PEKK or PEEK Extreme. Will these work?A
Q: Would recommend using either Glass filled PEEK or Vespel. Vespel screws are made from the highest temperature polymer available. Vespel has a usable limit of 300°C (572°F) in continuous heat and 500°C (932°F) intermittent.
