Plymouth, Michigan – Resinate Materials Group has been awarded an SBIR Phase One grant from the US Environmental Protection Agency. The grant is to fund process development of lignin polyols for use as flame retardant polyols in rigid insulating foam applications.
The company has patented a lignin polyol process that gives improved intumescence and FR performance in rigid foams, using sustainable materials including bio-renewable lignin and recycled polyethylene terephthalate.
‘A number of halogenated flame-retardants have been banned in recent years due to a variety of health and environmental concerns, leaving a potential performance gap in the rigid foam market,’ said Rick Tabor, Resinate’s chief technology officer. ‘The development of greener, less hazardous materials that can serve as an effective replacement is therefore an important safety need for modern society.’
