Resistance overview

PETG is not resistant (D) to Chloroform at 100 % 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

Chloroform is commonly encountered in electronics cleaning and cleaning and degreasing. 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 is not recommended for use with Chloroform. 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 FEP, PTFE, PVDF instead, which are rated A for this chemical and offer reliable long-term performance.

Did you know?

The chemical resistance of PETG depends not only on the chemical concentration but also on exposure time, mechanical stress, and the presence of other chemicals in the mixture.

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.
