WebOn heating in DSC, samples of UHMWPE show a single, fairly sharp, melting endotherm which may be increased to a peak temperature of 147°C and 77% crystallinity by annealing at elevated temperatures. An irreversible conversion of nascent to folded crystals, between 134 and 142°C, was observed by heating nascent UHMWPE powder in the calorimeter. Web28 Dec 2024 · Determine Weight Experimentally 1. Obtain a piece of the plastic. Identify the type of plastic you are testing and look up its mass density. 2. Measure the volume of the sample. Fill a large graduated cylinder with water to the 500 ml level. Immerse the piece of plastic completely in the water.
