Properties of the Teflon Hose:
Polytetrafluorethylene (PTFE) is an engineered plastic resin in the fluorocarbon group, the most commonly known of which is Dupont's trademarked Teflon. This high molecular weight resin displays outstanding chemical resistance to a remarkably wide variety of chemicals. The only known classes of chemicals that attack Teflon are the molten alkali metals such as sodium and potassium, and halogenated chemicals like fluorine gas or chlorine trifluoride. Other halogens and related compounds such as freon are known to effuse at a given rate.
The chemical compatibility of Teflon, combined with its other physical characteristics, make it the ideal engineered plastic for use in hose applications.
Flexible & Strong
Combined with metal braid, Teflon hose
can perform under high pressure and continuous flexing and vibration
conditions. Braided Teflon hose can withstand hundreds of thousands of
flex cycles without failure or fatigue.
Chemically Resistant and Inert
Teflon hose can handle an almost endless variety of fluids at extremes of pressure and temperature. It is the most universal hose known.
Wide Ranging Temperature
Hoses made of Teflon can typically withstand temperatures from -100°F to 500°F under most operating conditions. Even 350°F steam/cold water cycling is no match for Teflon.
Non-Stick, Low Friction
Almost no substances can adhere to Teflon. This property insures the purity of any fluid when transferred in a Teflon hose. It also allows for repeated reuse or alternate use with different fluids. With a coefficient of friction as low as 0.05, deposits cannot build up and flow rates are high throughout the hose life.
Resistant to Moisture
By its nature, Teflon lacks affinity to moisture. Absorption is less than 0.01%. In addition, no odor, taste, or color is added to the transfer fluid by Teflon, making it an FDA approved material for food contact.
Ageless
Weather, exposure, time...none of these affect the properties of Teflon. Teflon hose has limitless shelf life. It does not age.
