Expanded PTFE(eptfe) is a new type of medical polymer material, which is made of PTFE resin through special processing methods such as stretching. White, elastic and flexible, with a network structure formed by the connection of microfibers, these microfibers form countless pores, so that the expanded PTFE(eptfe) can be bent arbitrarily (over 360°), good hemocompatibility, biological aging resistance, used in the manufacture of artificial blood vessels, heart patches and other medical products.

Detailed Photos
From a medical point of view, Expanded PTFE(eptfe ) is the most ideal substitute for biological tissues.
Due to Expanded PTFE(eptfe) good biocompatibility and unique microporous structure, eptfe is non-toxic, non-carcinogenic, non-sensitizing and other side effects, and human tissue cells and blood vessels can grow into its micropores to form tissue connections, just like autologous tissues.
Medical implants
Because of expanded polytetrafluoroethylene (ePTFE) is pure inert, it can be used in a variety of rehabilitation solutions, including artificial blood vessels and patches for soft tissue regeneration and surgical sutures for vascular, cardiac, general surgery, and orthopedics, benefiting both physicians and patients.
Gasket & Sealant Industry
Expanded PTFE gaskets have good chemical resistance, anti-wear characteristics and strong resistance to high and low temperatures, making them ideal for the transportation and sealing of industrial liquids.
Industrial film technology
Expanded polytetrafluoroethylene (ePTFE) films can be processed into a variety of unique microstructures to produce a range of high-performance filter media with micropores that block particulates and allow air to pass through, and their industrial applications include chemical plants, incinerators, food and pharmaceutical manufacturing, foundry, and more.
Advanced dielectric materials for electronic devices
The inherent low loss and dielectric constant of expanded polytetrafluoroethylene (ePTFE) make it an ideal insulation material for wire and cable applications in many high-performance, challenging applications in the telecommunications, computer, test and measurement, defense, and aerospace markets.
