CHEMICAL RESISTANT CHART
(For Linear Detector material)
This chemical resistance chart cannot predict the effect on the
outer covering to complex chemical mixtures. The appropriate
chemical resistance tests using a representative sample of the
chemical(s) or a trial installation of the Linear Detector should
be performed to determine acceptable product performance.
