Material comparison at 20 °C
Resistance overview
PETG shows very good resistance (A) to Butanol at technical grade at 20 °C, meaning the material remains essentially unaffected by this chemical under standard laboratory test conditions. 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
Butanol is commonly encountered in cosmetics production and chemical synthesis. PETG (Polyethylene terephthalate glycol (co-polyester)) is a thermoplastic typically used for tanks, piping, containers and liners. Since Butanol 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 can be used with confidence for Butanol containment and handling. The A rating indicates that the material shows no significant change in weight, dimensions, or mechanical properties after prolonged contact under test conditions. This holds true at both 20 °C and 50 °C, giving a good safety margin for typical process environments.
Did you know?
Polyethylene terephthalate glycol (co-polyester) was first developed in the 1960s and remains one of the most widely used thermoplastics in chemical handling equipment.

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.
