Evaluation of Three Chemical Protective Clothing Materials for Selected Performance Properties
A study was conducted to evaluate selected properties of three different chemical protective clothing materials that are being considered for use by Dupont's DeLisle Site in Pass Christian, Mississippi for titanium chloride and related chemical service. Two of the materials represented new product offerings based on unique PTFE/fabric (HSF) laminates, while the third was a PVC/Nomex material currently used in chemical protective clothing at the Dupont DeLisle Site. The two PTFE/fabric laminates were further distinguished by the film thickness and type of surface finish. A number of tests were performed to measure permeation resistance against specific chemicals of interest: physical property testing to assess material strength and specialized tests to determine how the materials hold up to different environmental challenges (high temperature, cold temperature, and flame exposure). The study demonstrated how a series of test methods established by Committee F23 can be used to evaluate the material choices effectively for a specific set of chemical and physical exposure conditions.
