Frequently Asked Questions
Which materials resist Calcium Chloride at high concentrations?
The materials with an A rating (resistant) for Calcium Chloride 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 Calcium Chloride?
Yes. 3 of 16 tested materials show a worse rating at 50 °C than at 20 °C for Calcium Chloride. Materials affected include: PVC Rigid, SS 316, SS 304.
Is PTFE safe for Calcium Chloride?
PTFE is rated A for Calcium Chloride 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 Calcium Chloride?
Yes. Calcium Chloride is tested at 2 concentrations (aqueous, alcoholic solution). 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.
