Material comparison at 20 °C
Resistance overview
PETG has limited resistance (C) to Sodium Perborate at aqueous 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
Sodium Perborate is commonly encountered in waste treatment and bleaching. 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
No resistance data is available for PETG in contact with Sodium Perborate. Before using this combination, consult the material manufacturer or conduct independent testing.
Did you know?
When choosing between thermoplastics for Sodium Perborate service, engineers consider not just the resistance rating but also factors such as permeation rate, creep resistance, and weldability.

About PETG
PETG is a co-polyester for clear containers. Strong acids and alkalis and most organic solvents attack it.
Rating scale
- A very good resistance
- B good resistance
- C limited resistance
- D not resistant
- – no data
- K no general statement possible
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.
