Saimap Viennot: over 60 years of solid expertise

A story of mergers and growth

Founded in the 1950s, the companies SAIMAP and VIENNOT quickly earned a prominent position in the transformation of fluoropolymer materials. Their merger in 1991 gave birth to Saimap Viennot, consolidating their expertise at the production site in Saint-Lubin-des-Joncherets (Eure-et-Loir). The acquisition of ACEREF in 2011 further strengthened the company’s position in the transformation of thermoplastics, particularly fluoropolymers.

Today, with a 3,000 m² production parc machines and the commitment of around 40 employees, Saimap Viennot achieved a turnover of nearly €12.6 million in 2024, 65% of which comes from the aerospace and space sectors.
