Resistance to chemical agents

The table shows the behaviour of ELESA PEB and PES products in the presence of various chemical agents with which they may come into contact in an industrial environment (acids, bases, solvents, lubricants, fuels, aqueous solutions) and provides for three classes of behaviour:

good resistance = the product functional and aesthetic properties remain unchanged;

fair resistance = effects on the functional and/or aesthetic properties, depending on the type of product and the working conditions with some limitations of use according to the specific application;

poor resistance = product susceptible to chemical aggression. Not recommended for use.
