Resistance overview
PP is not resistant (D) to Diethyl Ether at technical grade and should not be used in direct contact. The chemical is expected to cause rapid degradation, which can include dissolution, cracking, severe swelling, or complete structural failure of the material.
Application context
Diethyl Ether is commonly encountered in pharmaceutical manufacturing and coatings and paints. PP (Polypropylene) is a thermoplastic typically used for tanks, piping, containers and liners. Since Diethyl Ether is flammable, material selection must also consider the risk of static charge buildup and the need for proper grounding in storage and transfer systems.
Practical recommendation
PP is not recommended for use with Diethyl Ether. The D rating indicates that the material will suffer rapid and severe degradation, which may include cracking, dissolution, severe swelling, or complete structural failure. Using this combination risks equipment damage, leaks, and potential safety incidents. Consider using Nylon (PA), PETG, Acetal (POM) instead, which are rated A for this chemical and offer reliable long-term performance.
Did you know?
Temperature is often the deciding factor when selecting materials for Diethyl Ether: even materials rated A at 20 °C may lose performance at elevated temperatures.

About PP
Polypropylene resists most acids, alkalis and salt solutions. Concentrated oxidising acids, chlorinated solvents and aromatic hydrocarbons attack it, and it turns brittle below about 0 °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.
