Odor: characteristic
Use: PLASTHALL TOTM imparts to PVC compounds excellent volatility resistance, due to its relatively higher molecular weight. PLASTHALL TOTM provides very low compound weight losses, exceptional retention of original elongation after air oven aging and excellent extraction resistance to a variety of polar and non-polar fluids. These properties abound for the broad usage of PLASTHALL TOTM in PVC wire and cable insulation and vinyl automotive interior trim. Of the trimellitate family, PLASTHALL TOTM is the most efficient.
