Home / News / What are the applications of expanded polytetrafluoroethylene?

Expanded polytetrafluoroethylene (ePTFE) is a new type of medical polymer material, made of polytetrafluoroethylene resin by special processing methods such as stretching. White, full of elasticity and flexibility, with a network structure formed by the connection of microfibers, these microfibers form countless pores, so that the expanded PTFE can be bent arbitrarily (over 360°), the blood compatibility is good, and it is resistant to biological aging. Used to manufacture artificial blood vessels, heart patches and other medical products. From the medical point of view, it is the most ideal substitute for biological tissue. Because of its good biocompatibility and unique microporous structure, it 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 tissue.
Multi-field applications
1. Medical implants
Because expanded polytetrafluoroethylene (ePTFE) is purely inert, medical products are highly biocompatible and will not cause rejection by the body. Expanded polytetrafluoroethylene (ePTFE) has a microporous structure and can be used in a variety of rehabilitation solutions, including artificial blood vessels and patches for soft tissue regeneration and surgical sutures for blood vessels, heart, general surgery and plastic surgery , So that doctors and patients can benefit from it. Our medical products can coexist with the body's own organization and restore its normal function.
2. Fluoropolymer fiber
Expanded polytetrafluoroethylene (ePTFE) fiber has the characteristics of high strength, low shrinkage, and abrasion resistance, and has strong ultraviolet resistance, thus ensuring its good stability and integrity in extreme environments.
The use of this fiber is very wide, it can be woven, woven, braided or sewn into a variety of fabrics, including compression packaging, sewing thread, construction fabrics and dental floss, etc.
3. Gasket and sealant
Expanded polytetrafluoroethylene (ePTFE) has good chemical resistance, abrasion resistance and strong resistance to high and low temperatures, and is very suitable for the transportation and sealing of industrial liquids.
