sera – Chemical Resistance Charts by sera group

sera is an app made by the sera group, which is based on resistance charts

to inform on the resistance of various materials against many different

liquid and gaseous chemicals. The choice of media and materials aims specifically

at the needs in mechanical and plant engineering with a focus on dosing, feeding and

compressor technology. As a leading supplier of system solutions in this area,

sera wants to offer a quick and easy overview about the resistance of relevant

materials to all planners, engineers, purchasers and interested persons.

The following materials were considered in the resistance charts:

PVC-U, PVC transparent, PP, PP-GFK, PE, PVDF, PVDF-GFK, EPDM, CSM, FPM, PTFE, PTFE-faced, FEP-covered, copper, brass, cast iron, 1.4571/1.4581, 1.4305/1.4104, 14.401, 1.4122v, Glas

Important note!

Resistance of materials is also dependant on other factors, e.g. operating conditions,

conditions of surface etc., and so this chart must be treated as an initial guide only.

It cannot claim to offer any guarantees. sera does not guarantee the accuracy of the information and

assumes no liability for any damages or losses incurred in connection with the use of the sera resistance chart.

It should be taken into conderation in particular that unusual dosing media are compounds

for the most part, and their corrosiveness cannot be deducted simply by adding the corrosiveness

of each single component. In such cases the chemical producer‘s data of the material compatibility

are to be conisdered as a matter of prime importance for the material choice. A safety data sheet

does not give these data and therefore cannot take the place of the technical documentaion on

the application.

The data has been taken from public sources, relevant manufacturer‘s documentation and our own tests. The hazardous materials identification was performed according to the Globally Harmonized System (GHS) for the EU.
