Resistance overview

PP is not resistant (D) to Turpentine Oil 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

Turpentine Oil is commonly encountered in cleaning and degreasing and electronics cleaning. PP (Polypropylene) is a thermoplastic typically used for tanks, piping, containers and liners. Since Turpentine Oil 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 Turpentine Oil. 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?

In industrial practice, PP components exposed to Turpentine Oil are typically inspected for swelling, discoloration, or loss of mechanical strength as early indicators of chemical attack.

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.

Rating scale

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.
