EPTFE
PTFE
Polytetrafluoroethylene (PTFE) is a high-performance fluoropolymer widely recognized for its exceptional chemical resistance, low friction, and ability to perform reliably under extreme temperatures. Commonly known by the brand name Teflon®, PTFE is an essential engineering material across industries where durability, purity, and long service life are critical. Its unique molecular structure gives it outstanding non-stick, insulating, and self-lubricating properties, making it ideal for demanding industrial and engineering applications.
EPTFE
Expanded Polytetrafluoroethylene (ePTFE) is a microporous, high-performance fluoropolymer material known for its exceptional chemical resistance, flexibility, and breathability. Produced by stretching PTFE under controlled conditions, ePTFE develops a unique node-and-fibril structure that provides a combination of strength, softness, and permeability. It retains the inherent properties of PTFE, including low friction, thermal stability, and chemical inertness, while offering improved conformability and sealing performance. ePTFE is widely used in applications such as gaskets, seals, filtration membranes, vents, and medical and industrial components where reliable sealing, airflow, and contamination resistance are essential.
