Welcome to Sonderhoff USA, LLC!

Sonderhoff USA, LLC – a part of the Sonderhoff enterprise group – was founded in 2003 with the goal of making FIPFG (Formed-In-Place Foam Gasket) technology well known across the North American continent and producing sealing and potting materials in the region of our own initiative. For this fully automated application process for fluid seals for housings is not as widespread in America as it is in Europe. Thus we sought direct contact with our customers and now provide the most important automotive, electronics and packaging industry suppliers with FERMAPOR K31 foam seals and FERMADUR potting systems.

And we are certain that automation of the application processes for fluid and thixotropically applied FIPFG seals will present itself more and more in the NAFTA market as the industry standard.

For our customers it is thus very advantageous that Sonderhoff USA, LLC is a system supplier, that is, offering machine, material and service in the same package. For Sonderhoff is not only the producer of the material components of fluid sealing systems, but also offers its own mixing and dispensing technologies, automation solutions and job order production.

Think global act local – our services for our American clients

Our products are used worldwide with great success – at least 300 million products are processed yearly using our machines and materials. This expertise for the foam sealing, gluing and potting processes is offered to the north-American market tailor-made on location:
