Properties and applications of PTFE tubes

What is PTFE tubing?

PTFE is a white powder discovered by DuPont Laboratories in 1938, initially used in the military industry and then for civilian use in 1945. Because of its excellent properties, it is commonly known as the "King of Plastics".

PTFE tubing has the following characteristics

Low coefficient of friction. Coefficient of friction ≤ 0.1, PTFE products can be used as lubrication products corrosion resistance. PTFE tube is resistant to strong acids and bases and almost all chemicals do not react (high temperature and fluorine and alkali metal reaction), can resist "aqua regia" corrosion. Self-cleaning. PTFE is difficult to adhere to, and no solid material is known to adhere to it. Even if there is a little adhesion, it can be cleaned off by simple methods and is not flammable. Teflon material is insoluble material, even 400 ℃ will not melt, only softened high temperature resistance. PTFE Teflon material can withstand high temperature up to 260℃ and low temperature up to -70℃ with high resistance. Teflon tube has high resistance, excellent insulation performance, and can withstand 10,000 volts of voltage anti-aging. Teflon tube has excellent anti-aging properties and long service life.

PTFE has been used in more than 200 industries over the past two decades, and while sheets, rods, coatings and components make up the majority of the PTFE product market, PTFE tubing is now becoming a major growth area. PTFE tubing has been used in a variety of applications including automotive, chemical, electrical and medical.

PTFE tubing applications.

Automotive industry. PTFE's ability to withstand temperatures in excess of 260°C makes it ideal for high temperature fluid transfer.

Medical industry. PTFE tubing is in high demand in medical applications due to its lubricity and chemical inertness. PTFE tubing can be inserted into the body without fear of reaction or abrasion to any part of the body.

Chemical industry. In chemical applications (including laboratories), PTFE is inert and durable, making it an ideal replacement for glass.

Electronics industry. In electrical applications, PTFE's excellent dielectric properties make it ideal for insulating high-voltage cables.
