General Plastics Manufacturing Co. (Tacoma, WA, US) featured its fire, smoke, and toxicity- (FST) compliant polyurethane foam cores — the FR-3800 FST series — and its molded parts program. As the first halogen-free polyurethane foam that satisfies FST requirements and Ohio State University (OSU) 55/55 standards, General Plastics’ LAST-A-FOAM FR-3800 FST Performance Core Series is available in densities of 3-40 lb/ft3. The product's mechanical properties are similar to the FR-3700 and 6700 aerospace-grade core material series, which also meet FST and OSU requirements. It withstands process temperatures up to 154°C, providing a larger processing window to manufacture composite parts.
