Divinycell F foam is a recyclable, prepreg compatible sandwich
core offering excellent Fire, Smoke and Toxicity (FST) properties,
good mechanicals and processing characteristics. It meets the
US and European regulatory requirements for commercial aircraft
interiors. Other key features include vacuum bag processing up
to 220 C and matched tooling and press processing up to 220 C,
exceptional fatigue life, good chemical resistance and excellent
heat ageing at 180 C. Divinycell F is compatible with most common
aerospace composite manufacturing processes.
