FEP-encapsulated O-rings offer optimal solutions as specialty seals for demanding applications in the pharmaceutical industry and food technology. These high-performance seals combine the mechanical properties of elastomeric core materials with the exceptional chemical resistance of fluorinated ethylene propylene (FEP).

Technical Properties and Material Variants:

• FEP-Encapsulated FPM O-Rings: Shore hardness A 75°, operating temperature -20°C to +200°C
• FEP-Encapsulated Silicone O-Rings: Shore hardness A 70°, operating temperature -60°C to +200°C

The FEP encapsulation ensures universal chemical resistance against concentrated acids and bases, vegetable and animal oils, as well as all polar media. These properties correspond nearly to the resistance of PTFE.

Pharmaceutical and Food Compliance:

Both variants meet FDA and BfR conformity as well as the requirements of the European Pharmacopoeia. The FPM core variant complies with USP Plastic Class VI at +121°C. Sterilization temperatures are +121°C for pharmaceutical applications and +149°C for the food industry. During cleaning processes, the seals withstand temperatures up to +280°C.

The seals are characterized by exceptional weather, aging, and ozone resistance. Their high abrasion resistance ensures long service life even under mechanical stress.
