DIFFERENTIAL SCANNING CALORIMETRY METHOD TO DETERMINE THE LIFE-SPAN OF PP (POLYPROPYLEN) TEXTILE USED FOR FLEXIBLE WATER BLADDER

Abstract

The life-span of outer cover materials determines the work life of flexible water bladder. Accuracies of predictions depend on whether the prediction equation sufficiently includes the factors that impact on flexible water bladder such as climate, weather, environment and use conditions and whether the selected sample damage criteria are typical. Acceleration of aging enables quicker evaluation of material decomposition. This article shows results of flexible water bladder life-span prediction with differential scanning calorimetry method
