Resistance overview

PTFE shows very good resistance (A) to Cyclohexanone at technical grade at 20 °C, meaning the material remains essentially unaffected by this chemical under standard laboratory test conditions. The rating remains stable between 20 °C and 50 °C, which means this material can also handle moderately elevated process temperatures without additional risk.

Application context

Cyclohexanone is commonly encountered in chemical synthesis and electronics cleaning. PTFE (Polytetrafluoroethylene) is a fluoropolymer typically used for seals, gaskets, valve seats and lined equipment. Since Cyclohexanone 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

PTFE can be used with confidence for Cyclohexanone containment and handling. The A rating indicates that the material shows no significant change in weight, dimensions, or mechanical properties after prolonged contact under test conditions. This holds true at both 20 °C and 50 °C, giving a good safety margin for typical process environments.

Did you know?

Chemical resistance testing according to DIN and ISO standards typically evaluates weight change, dimensional change, and retention of tensile strength after immersion.

About PTFE

PTFE is resistant to almost every chemical in this list. The known exceptions are molten alkali metals, elemental fluorine and some fluorinating agents at elevated temperature.

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.
