Abstract
Sorage modulus(G'), Impact and rebounding properties of polyurethane(PU), phylon(PH) and injection phylon(IP) foams were studied. The storage modulus of PU foam was dramatically increased with decreasing temperature. But the storage modulus(G') of IP and PH foams were not affected by temperature. The Impact force of PU foams was increased with decreasing temperature. But in the cases of IP and PH foams, the impact forces were not changed with temperature below $20^{\circ}C$. Impact farces of IP and PH foams were increased with the temperature above $20^{\circ}C$, but that of PU foam was not changed. Rebounding resilience of PU foam was lower than those of IP and PH foams from $-20^{\circ}C$ to $40^{\circ}C$.
