ABSTRACT:
It has been discovered that particular flexible polyurethane foam formulations having a chlorinated alkane incorporated therein have the advantage of improved combustion resistance, but also unexpectedly the additional advantages of improved durability (dynamic fatigue), and better processing in terms of a delayed onset of gel. These results were surprisingly achieved with the use of a chlorinated alkane as the sole component to improve combustion resistance. Incorporation of as much as 34 parts of chlorinated alkane per hundred parts of polyol have been accomplished.
