High-Performance ePTFE Products by Peflon
Peflon manufactures expanded PTFE (ePTFE) sheet gaskets, joint sealant, microporous membranes, and thin-walled tubing. Our porous, flexible, chemically inert material delivers reliable sealing, filtration, and biocompatible performance from −200 °C to +260 °C.
What is Peflon ePTFE?
Peflon ePTFE is expanded polytetrafluoroethylene, made by stretching PTFE to create a porous micro-structure. It is soft, flexible, and very strong. It resists heat and chemicals and is safe for the body, so it is used in medical implants like grafts, meshes, and tubes. It also works in filters, vents, and seals for electronics, chemicals, and food. Glovemaking uses ePTFE for waterproof yet breathable fabrics. The special structure lets air pass, blocks liquid, keeps dirt out, and stays durable.

Peflon ePTFE Product Categories
Peflon offers a diverse range of expanded PTFE products, each engineered for specific applications and performance needs. Our categories are designed to help you quickly find the ideal solution for your project, whether you need superior sealing, advanced filtration, or biocompatible materials.
ePTFE Sheet Gaskets
Peflon ePTFE sheet gaskets are ideal for large or complex flange applications. They are designed for superior chemical and temperature resistance.
ePTFE Joint Sealant
Our joint sealant is a flexible, form-in-place gasket material that eliminates the need for pre-cut gaskets. It’s easy to install and highly resistant to creep and cold flow.
Microporous ePTFE Membranes
Used in air and liquid filtration, these membranes offer high flow rates with excellent particle retention. They are a key component in vent and filter cartridges.
Thin-Walled ePTFE Tubing
This tubing is perfect for medical device manufacturing and fluid transfer systems where purity and chemical inertness are critical.

Frequently Asked Questions about ePTFE
What makes ePTFE different from regular PTFE?
ePTFE is produced by expanding PTFE into a microporous, fibrillated structure. Regular PTFE is dense and solid, while ePTFE is soft, lighter, and permeable to air while still blocking liquids. This makes ePTFE far better for sealing, filtration, and medical uses where flexibility and porosity matter.
Is Peflon’s ePTFE biocompatible for medical use?
Yes, our ePTFE products are manufactured to strict standards and are suitable for many medical applications. We can provide detailed information and certifications to meet your specific project requirements.
What are the main applications for ePTFE membranes?
ePTFE membranes are primarily used in high-efficiency filtration. They are key components in filter cartridges for air, water, and chemicals, as well as in vents for protective enclosures.
Can Peflon provide custom ePTFE gaskets for my project?
Absolutely. Our engineering team specializes in creating custom ePTFE solutions, from unique sheet sizes to intricate gasket designs. Just share your specifications with us.
How does ePTFE perform in high-temperature environments?
ePTFE maintains its physical and electrical properties across a wide temperature range, from −200 °C to +260 °C. This makes it a preferred material for high-temperature sealing and insulation.
