DESIGN & ENGINEERING DATA
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
Chemical Resistance
PVC, ABS and CPVC piping systems have very different
chemical resistance. Review manufacturer's literature for
all chemicals coming into contact with the piping materials
prior to use.
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
