PTFE - The Optimum ChoiceFor Hose Linings

PTFE, or Polytetrafluoroethylene, comprises long-chainmolecules of carbon atoms, each linked to two fluorine atoms.The fluorine atoms provide a helical spiral which surroundsthe carbon chain and protects it.It is this structure which creates the unique properties forwhich PTFE is well-known. Section from a PTFE Molecule,16 Angstrom Units long. Excellent Chemical Resistance
PTFE is renowned as the most chemically resistant material known. Only a very few, very unusual substances and conditions can affect it, like Fluorine gas at high temperature and pressure and Liquid, boiling sodium metal.PTFE lined hoses can therefore be used for a wider variety ofchemicals than any other hose type, making it the ideal choice for very corrosive chemical applications and multi- product applications.

Non-Stick Surface
The use of PTFE as a surface for cookware products has demonstrated to the world how easily cleanable PTFE surfaces are.This means that PTFE lined hoses can be purged 100%clean more quickly, easily and reliably than any other type of hose. Excellent Temperature Range
The cookware application also demonstrates another of PTFE’s many attributes - temperature resistance. PTFE itself can be used as a hose liner at temperatures from -150ËšC up to +260ËšC, dependent upon the hose design and the application conditions.This is the widest temperature range of any rubber or plastichose lining material. Hose Design
The only issue with PTFE as a hose lining material is the best way it can be integrated in to the hose design. This is where Aflex Hose have a proven record of success over the last 30 years.
