Products for
 Chemistry & Petrochemistry

In the chemical and petrochemical industries, materials are permanently exposed to extreme conditions.

Lézaud offers a wide range of products from hoses, round cords, profiles, sheets and foils as well as stoppers for chemically demanding applications.

Chemical resistance, temperature stability and media compatibility place the highest demands on materials.

Based on our extensive database on the chemical resistance of plastics, TPEs and elastomers, we provide targeted advice and develop customised solutions - tailored to the process, medium and application environment.
