High Performance in Demanding Environments
The chemical industry relies on precise, high-quality molded parts and seals. Reliability and durability are particularly important here to ensure low-wear, long-lasting processes. Fietz materials, especially PTFE, are ideally suited to meet the specific requirements of the chemical industry.

Fietz materials in the chemical industry
In the chemical industry, Fietz uses not only PTFE (FiKumer®) – which is widely used in the chemical industry due to its exceptional chemical and thermal resistance – but also many other thermoplastics.
Materials from the FiMasol® portfolio, in particular, are especially suitable for the chemical industry, depending on the medium, temperature, mechanical stress, and regulatory requirements.
Fietz also offers targeted product solutions made from high-temperature plastics (e.g., PEEK) that are mechanically robust and chemically resistant. The Fietz Group specializes in manufacturing these materials using injection molding and machining processes.
