PFAS-Free* Solutions & Materials

With growing regulation over Per- and PolyFluoroAlkyl substances, a transition towards alternative materials has become critical to supply chain management throughout the industry. Omniseal Solutions partners with our customers and suppliers to find and develop advanced materials & components for critical applications anticipating key changes in our markets.

Due to their unmatched combination of physio-chemical properties, Fluoropolymers, a sub-family of PFAS, have been used by Omniseal Solutions for decades on numerous challenging applications in various Industries. However, other materials have been developed and used already over years across our different markets. The recent changes in the regulatory environment accelerated our efforts towards the research and development of alternative materials for our customers’ applications.

Our teams of engineers are very well known throughout the industry as technology leaders in sealing technology and beyond, through a strong material expertise, a high design creativity coupled with a wide range of application testing and material simulation capabilities. We have developed and continue to invest in diverse production capabilities that provide us with a versatile manufacturing infrastructure able to supply any high performance metal and plastics parts.

You can find more of those alternatives in the page below or contact us to know more and explore the alternatives with our engineers.

* PFAS-Free here means we do not intentionally add PFAS material in the product, but does not exclude the possibility of traces, as these materials are common in the environment.

Hycomp Composites

H310® & H320® Materials

These composite solutions are high temperature, polymer-based materials that are reinforced with glass or carbon fibers. They are used as a replacement for metal due to weight saving properties and eliminating lubrication need in applications with high mechanical requirements. Suited for aviation critical systems such as engine, flight control, landing gear, wheel and braking, applications vary from bushings, guide rings, wear liners, seals, clamps, and thermal isolators.
