Material comparison at 20 °C
Resistance overview
PETG has limited resistance (C) to Vinyl Acetate at technical grade 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. The rating remains stable between 20 °C and 50 °C, which means this material can also handle moderately elevated process temperatures without additional risk.
Application context
Vinyl Acetate is commonly encountered in electroplating and chemical storage. PETG (Polyethylene terephthalate glycol (co-polyester)) is a thermoplastic typically used for tanks, piping, containers and liners. Since Vinyl Acetate 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 has limited resistance to Vinyl Acetate 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, LDPE, Nylon (PA), PP offer significantly better resistance and are rated A.
Did you know?
In industrial practice, PETG components exposed to Vinyl Acetate 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.

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.
