Teflon® Encapsulated O-Rings: Understanding the Name
Teflon® Encapsulated O-Rings: Understanding the Name is widely used in the industry. It serves as a general descriptor for O-rings encapsulated with fluoropolymers from the Teflon® family. Our encapsulated O-rings specifically use FEP (Fluorinated Ethylene Propylene) or PFA (Perfluoroalkoxy Alkane). However, these materials are part of the Teflon® family and share its hallmark characteristics.
Teflon® FEP Encapsulated O-Rings
To explain further, Teflon® is a registered trademark of Chemours. It represents a broad range of high-performance fluoropolymers. Both FEP and PFA fall under this family because they offer similar benefits. For example, they provide exceptional chemical resistance, low friction, and high-temperature tolerance. As a result, calling them “Teflon® Encapsulated O-Rings” simplifies communication. It also leverages the widespread recognition and trust associated with the Teflon® brand.
Understanding the Specific Materials: FEP and PFA
Teflon® Encapsulated o-rings: Understanding the name and that both FEP and PFA belong to the Teflon® family, they offer distinct properties that suit different applications. FEP delivers excellent chemical resistance, transparency, and low permeability, which make it perfect for environments that demand robust chemical performance at a lower cost. In contrast, PFA handles higher temperatures (up to 260°C/500°F) and provides superior mechanical strength, making it ideal for demanding applications in industries like pharmaceuticals and semiconductors.
Unlike PTFE (the most recognized Teflon® material), FEP and PFA function as thermoplastics, which allows manufacturers to extrude and mold them. This property plays a key role in forming the encapsulation that surrounds the elastomer core of the O-rings. PTFE, on the other hand, remains rigid and non-melt-processable, making it unsuitable for encapsulation.
Why the Name Matters
Calling our products “Teflon® Encapsulated O-Rings” provides a clear and recognizable description. It emphasizes their association with the Teflon® family’s exceptional performance standards. Nevertheless, we are committed to transparency. When you order from us, we specify whether the encapsulation is FEP or PFA. We can also provide detailed material certifications upon request.
