Material comparison at 20 °C
Resistance overview
PVDF has limited resistance (C) to Methyl Acrylate 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. 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
Methyl Acrylate is commonly encountered in coatings and paints and chemical synthesis. PVDF (Polyvinylidene fluoride) is a fluoropolymer typically used for seals, gaskets, valve seats and lined equipment. Since Methyl Acrylate 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
PVDF has limited resistance to Methyl Acrylate 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, Aluminium offer significantly better resistance and are rated A.
Did you know?
When choosing between fluoropolymers for Methyl Acrylate service, engineers consider not just the resistance rating but also factors such as permeation rate, creep resistance, and weldability.

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