DUNA-USA (Baytown, TX, US) introduced at CAMX 2015 in Dallas, TX, US, its new  BLUE CORINTHO HT high-temperature polyurethane tooling board, designed for prototyping, prepreg composite layup tooling and master plug and moldmaking. BLUE CORINTHO HT features a Tg of 265°C and low thermal conductivity to provide what is said to be a stable platform for producing accurate master models and layup tools. DUNA-USA commissioned Stealth Composites (Philadelphia, PA, US) to conduct prepreg composite layup tests with the BLUE CORINTHO HT as a master mold. Stealth produced carbon fiber parts at autoclave temperatures of 250°F and 350°F and says higher temperatures might be possible. Other reported features of BLUE CORINTHO HT include easy machinability, easy handling and affordability.
