Products for
 Chemical industry

In the chemical industry, materials and sealing solutions are exposed to aggressive media, high temperatures, and demanding process conditions.

Lézaud offers Hoses, Round cords, Profiles, Sheets as well as flat seals and O-rings for various applications in the chemical industry and related process sectors.

Crucially, this involves reliable chemical resistance, secure sealing, and suitable materials for contact with acids, alkalis, and solvents. Based on our material expertise in plastics, TPEs, and elastomers, we provide targeted advice on selecting appropriate solutions – tailored to the medium, process, and technical demands.
