Resistance overview

PVDF shows excellent resistance to Salicylic Acid across all 2 tested concentrations (saturated, powder) at 20 °C, making it a reliable choice for storage, transfer, and handling applications involving this chemical at any of the tested strengths. 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

Salicylic Acid is commonly encountered in chemical processing and laboratory work. PVDF (Polyvinylidene fluoride) is a fluoropolymer typically used for seals, gaskets, valve seats and lined equipment. The compatibility between these two is therefore an important consideration for engineers and procurement teams selecting containment, transfer, or processing equipment.

Practical recommendation

PVDF can be used with confidence for Salicylic Acid 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?

The ratings shown here apply to pure Salicylic Acid in contact with the base fluoropolymer. In real-world applications, additives, pigments, and fillers in the material can shift resistance in either direction.

About PVDF

PVDF resists acids, halogens and hydrocarbons. Strong bases, amines, ketones and esters attack it. Service temperature is up to about 150 °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.
