Material comparison at 20 °C
Resistance overview
HDPE has limited resistance (C) to Chloroform at 100 % 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. However, at 50 °C the resistance rating drops, indicating that temperature must be factored into the design. For heated applications, additional testing under actual service conditions is strongly recommended.
Application context
Chloroform is commonly encountered in electronics cleaning and cleaning and degreasing. HDPE (High-density polyethylene) 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
HDPE has limited resistance to Chloroform and should only be used for short-term or intermittent contact at ambient temperature. The C rating means the material undergoes noticeable changes — swelling, loss of strength, or surface degradation — that make it unsuitable for permanent installations. For prolonged or continuous exposure, FEP, PTFE, PVDF offer significantly better resistance and are rated A.
Did you know?
In industrial practice, HDPE components exposed to Chloroform are typically inspected for swelling, discoloration, or loss of mechanical strength as early indicators of chemical attack.

About HDPE
High-density polyethylene resists most aqueous acids, alkalis and salt solutions. Strong oxidising acids, chlorinated solvents and aromatic hydrocarbons attack or swell it. Continuous service is usually limited to about 80 °C.

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.
