Resistance overview
PETG is not resistant (D) to Cyclohexanone at technical grade and should not be used in direct contact. The chemical is expected to cause rapid degradation, which can include dissolution, cracking, severe swelling, or complete structural failure of the material.
Application context
Cyclohexanone is commonly encountered in chemical synthesis and coatings and paints. PETG (Polyethylene terephthalate glycol (co-polyester)) is a thermoplastic typically used for tanks, piping, containers and liners. Since Cyclohexanone is flammable, material selection must also consider the risk of static charge buildup and the need for proper grounding in storage and transfer systems.
Practical recommendation
PETG is not recommended for use with Cyclohexanone. The D rating indicates that the material will suffer rapid and severe degradation, which may include cracking, dissolution, severe swelling, or complete structural failure. Using this combination risks equipment damage, leaks, and potential safety incidents. Consider using HDPE, Nylon (PA), Acetal (POM) instead, which are rated A for this chemical and offer reliable long-term performance.
Did you know?
Chemical resistance testing according to DIN and ISO standards typically evaluates weight change, dimensional change, and retention of tensile strength after immersion.

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

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.
