Frequently Asked Questions
Which materials resist Sodium Perborate at high concentrations?
The materials with an A rating (resistant) for Sodium Perborate at 20 °C are: PTFE, HDPE, PP, PVDF, PVC Rigid, EPDM, Viton (FPM), SS 316. These can generally be used in direct contact.
Which materials should be avoided with Sodium Perborate?
Materials rated D (not resistant) for Sodium Perborate are: Nylon (PA). These should not be used in contact with Sodium Perborate.
Does temperature affect chemical resistance to Sodium Perborate?
For Sodium Perborate, all tested materials maintain the same rating at both 20 °C and 50 °C.
Is PTFE safe for Sodium Perborate?
PTFE is rated A for Sodium Perborate at 20 °C. A rating of A means resistant, B means limited resistance, C means partly resistant, and D means not resistant.
Does concentration affect chemical resistance to Sodium Perborate?
Yes. Sodium Perborate is tested at 2 concentrations (aqueous, saturated). Some materials change their rating depending on the concentration.
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.
