XANTAR®, XANTAR® C and XANTAR® E grades are resistant against many substances, although some chemical agents may attack under certain circumstances. The chemical resistance of XANTAR®, XANTAR® C and XANTAR® E grades not only depends on the nature of the substance or chemical it is exposed to, but also on the concentration, the temperature, the exposure time, the molecular weight and the stress (which can be a result of moulding and/or external loading). In general, modified XANTAR® grades and XANTAR® blends will be less sensitive to environmental stress cracking compared to standard XANTAR® grades. For most demanding applications, where environmental stress cracking should be as low as possible at both high and sub-zero temperatures, XANTAR® XRM grades are developed.

The comprehensive table on the next page gives a general overview of the chemical resistance of XANTAR®. This overview merely gives indicative information. In order to determine the actual chemical resistance under practical circumstances, a basic test procedure is available at our Technical Center in Geleen, The Netherlands. The test allows us to easily establish the effect of a chemical agent on a selected grade under certain combinations of time, temperature and stress. For highest accuracy it is recommended to determine the performance under 'real life' conditions.
