Positive (-Pos) CTE / ZTE Carbon Fiber Tube │Rock West Composites

Near zero CTE, slightly positive ◾ High modulus carbon fiber◾ Aerospace quality tubing◾ Plain weave finish◾ Low outgassing certified

ZTE Carbon^TM Tubes are a precision product that is commercially produced. It is an excellent choice for structures requiring dimensional stability. Our tubes are engineered to have essentially no residual distortion (hysteresis) in elongation, bend or twist after exposure to high or low temperatures. We validate the CTE performance with an in-house optical metrology system. Our positive ZTE Carbon tubes have a CTE < 0.1 parts per million/°F for elongation.
