Frequently Asked Questions
Which materials resist Sodium Carbonate at high concentrations?
The materials with an A rating (resistant) for Sodium Carbonate at 20 °C are: PTFE, HDPE, PP, PVDF, PVC Rigid, EPDM, Viton (FPM), NBR. These can generally be used in direct contact.
Does temperature affect chemical resistance to Sodium Carbonate?
Yes. 2 of 17 tested materials show a worse rating at 50 °C than at 20 °C for Sodium Carbonate. Materials affected include: PVDF, Aluminium.
Is PTFE safe for Sodium Carbonate?
PTFE is rated A for Sodium Carbonate 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 Carbonate?
Yes. Sodium Carbonate is tested at 3 concentrations (aqueous, saturated, concentration not stated). 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.
