DESIGN & ENGINEERING DATA
Chemical Resistance
The following table gives the chemical resistance of ABS, PVC and CPVC thermoplastic piping materials and three commonly
used seal materials. The information shown is based upon laboratory tests conducted by the manufacturers of the materials, and
it is intended to provide a general guideline on the resistance of these materials to various chemicals. NOTICE: This table is not
a guarantee, and any piping systems using products made of these materials should be tested under actual service conditions to
determine their suitability for a particular purpose. See website for most current data: www.charlottepipe.com
