Effects of Foam Density and Content on Puncture Resistance and Cushioning Properties of PU/ Vermiculite Foam Composites

Abstract:

This study presents effects of foam density and vermiculite content of puncture resistance and cushion properties of PU/vermiculite foam composite for resisting against sharp objects and impact load. Results show that puncture resistance property improves significantly with foam density and slightly with increase of vermiculites. Cushion property becomes worse lower after vermiculite addition. With improvement of foam density, cushion property shows an uncertain trend. Besides, comparing with different contents of vermiculites, PU/vermiculite foam composite containing 5 wt% vermiculite has the lowest cushion property because vermiculite bonds with polar group among polar group among PU molecular.
