Flame retardant polyurethane foams with starch unit

Polyurethane foams with incorporated starch described in up to date literature have good functional properties except flame resistance. Their oxygen index falls within 19.3–20.5%, while flame rate is 2.25–12.50 mm/s. We have obtained and tested polyurethane foams with following flame retardants: mel...
