PTFE Film

PTFE Film is widely used in electrochemical applications due to its chemical resistance and thermal stability. It serves as an insulating barrier in lithium-ion batteries and fuel cells, preventing short circuits and ensuring consistent performance. In research laboratories, PTFE film is essential in microfluidic devices, offering non-stick, low-friction surfaces for precise fluid control. It is also used in gaskets, seals, and filtration membranes that require resistance to high temperatures and aggressive chemicals. With a high melting point and low surface energy, PTFE film is a key material in engineering applications such as energy storage, surface coatings, and fluid handling systems, providing reliable performance in harsh conditions.
