Semi-flexible, shock-absorbing polyurethane foams containing an amylaceous material, such as a cereal starch or flour, and having an open cell structure are prepared by co-reacting the amylaceous material and a polyether with an aromatic polyisocyanate having a functionality of about 2 to about 2.4. The foams are particularly useful in crash padding.
