Polytetrafluoroethylene (PTFE), to give it is full chemical name, was discovered in 1938 by DuPont scientist Dr. Roy Plunkeet. PTFE is plastic resin in the Fluorocarbon group.

PTFE Hoses
PTFE hoses are an ideal problem solver for fluid transfer applications involving aggressive chemicals, extremes of temperature/pressure, extreme movement /vibration, or where hygiene is paramount.

Chemical resistance
The PTFE Hose liner is virtually inert to all chemicals and solvents. It is resistant to fuming Sulphuric and Nitric acids, Amines, Antioxidants and Methanol. It is only known to react with elemental Alkali metals (molten or in solution), Fluorine and Chlorine Trifluoride.

Vacuum performance
To ensure the selection of the right hose for a particular application, it is important to understand the potential effects of vacuum and its relationship to hose construction. Vacuum is also properly referred to as negative pressure which future helps to explain its effect on hose.
