FEP-/PFA-encapsulated seals consist of an elastic core – such as FKM, VMQ, or EPDM – which is seamlessly enclosed by a thin-walled jacket of FEP or PFA. The jacket thickness depends on the inner diameter and the cross-section of the O-ring.
The properties of FEP and PFA are similar to those of pure PTFE and offer almost complete resistance to solvents and chemicals. At the same time, the elastomer core provides the necessary flexibility and resilience.
This combination opens up new application possibilities in demanding areas such as the chemical, oil and gas industry, mechanical engineering, or food technology. Chemical resistance is maintained even under demanding conditions.
The result: flexible and chemical-resistant seals for extreme operating conditions.
