Material comparison at 20 °C
Resistance overview
PETG has limited resistance (C) to Perchloroethylene (PCE) at 20 °C. This indicates that the chemical has a noticeable effect on the material, which may include visible swelling, softening, or a measurable loss of tensile strength. Use is generally limited to short-term or intermittent contact where full structural integrity is not required. However, at 50 °C the resistance rating drops, indicating that temperature must be factored into the design. For heated applications, additional testing under actual service conditions is strongly recommended.
Application context
Perchloroethylene (PCE) is commonly encountered in bleaching and waste treatment. PETG (Polyethylene terephthalate glycol (co-polyester)) is a thermoplastic typically used for tanks, piping, containers and liners. The compatibility between these two is therefore an important consideration for engineers and procurement teams selecting containment, transfer, or processing equipment.
Practical recommendation
PETG has limited resistance to Perchloroethylene (PCE) and should only be used for short-term or intermittent contact at ambient temperature. The C rating means the material undergoes noticeable changes — swelling, loss of strength, or surface degradation — that make it unsuitable for permanent installations. For prolonged or continuous exposure, Acetal (POM), ECTFE/ETFE, FEP offer significantly better resistance and are rated A.
Did you know?
In industrial practice, PETG components exposed to Perchloroethylene (PCE) are typically inspected for swelling, discoloration, or loss of mechanical strength as early indicators of chemical attack.

About PETG
PETG is a co-polyester for clear containers. Strong acids and alkalis and most organic solvents attack it.
Rating scale

A rating marked * is an estimate in the source, not a test result. An estimate is given as one value without a temperature.
About this data
The ratings come from the chemical resistance list published by Bürkle GmbH, which compiled them from raw-material manufacturers’ data. They describe laboratory tests on the raw material at 20 °C and 50 °C.
A finished part also sees pressure, mechanical stress, welds and mixtures that a laboratory test does not. Treat the rating as a first filter and test under your own conditions before relying on it.
