Materials with a colorimetric memory response to compression

VALUE PROPOSITION The ability to detect compression-based end-of-life for materials is important in any application where foam padding is used. There is a need to determine if padding is performing to specification. There is no simple way to determine when foam materials have degraded to the point of being no longer useful. The degradation of such...
