ADVANTAGES
:
PTFE
(POLY TETRA FLUORO ETHYLENE) is an engineering plastic in the fluorocarbon
group, the original being Dupont's Teflon. It had tremendous potential in
industrial and commercial application. The chemical compatibility of PTFE,
combined with its other physical characteristics make it the ideal hose in
today's industry.
The
flexibility of PTFE hose remains constant even after long and continuous use of
extreme pressure and temperature (-73oC +260oC). It
remains completely functional down to cryogenic temperature. PTFE hose has high
resistance to steam, chemicals, solvents, pressure impulses, flexing and
vibration from flex fatigue.
EXCELLENT
CHEMICAL RESISTANCE :
PTFE
is one of the most chemically resistant substances known, similar to ceramics.
It will chemically resist virtually all gaseous and fluid corrosives, and is
totally unaffected chemically by all acids, alkalis, solvents, fuel oils,
detergents and food stuffs except molten alkalai and fluoride compounds.

LONG
SERVICE LIFE :
The
flexibility of PTFE hose remains constant, even after long and continuous use at
high temperatures. Since the hose is also relatively unaffected by chemicals,
the service life of the hose is usually longer than that of other types of
rubber or plastic hose. Greater reliability and reduced maintenance costs can
therefore be expected.
NON-STICK
:
Hose
easily cleaned to maintain batch purity, when using one hose for several
services. Efficient, clean transfer through the hose is achieved without any
material becoming trapped as it passes through the hose bore. Internal bacteria
traps are therefore avoided due to this non-stick nature of PTFE.
FOOD
SUITABILITY :
Suitable
for food stuff conduits as teflon is physiologically unobjectionable and
no transfer of taste or colour.
BIO
- DEGRADATION :
Resistance
to enzymatic and microbiological attack, does not contain addictives which may
provide a sub-strate for fungal or bacterial growth.
END
CONNECTION :
A
range of end connections is available to the customers requirements.
