PFA UV lamp tube, UV lamp protected cover, PFA UV lamp cover , PFA
shrink tube
Introduction:
PFA shrink tube is made from PFA resin and prepared by the
technology of thermoplastic extrusion and blowing. It has
non-sticking, heat-resistance, aging resistance, corrosive
resistance, non-flammability and good electric property.It can besolid adhesive for PTFE and also a good adhesive for laminating
various materials. Its working temperature isup to
260 and is an ideal material for circuit board and flat cable.
Usage :
Office-work machine 's roll packing
paper machine's roll packing
printing and dyeing machine's roll packing
printing machineroll packing
insulated jacket
the main insulation of rotor of the electric instrument
water treatment
make the magma sample in the field of oil field ect.
UV lamp protecting
FEP & PFA has perfect anticorrosive properties and heat resistance
and electric resistance. they are widely used in the fields of
electrical,petrochemical,industrial,IT industrial.They are the
perfect material so making VU lamp protection tube, anticorrosice
tube
PFA is both transparent to UV-A and UV-C light and totally
resistant to it as well as being temperature resistant. Therefore
,it makes an excellent material for shatter proofing UV lamps used
in the food industry where glass free areas are required. Other
plastic voerings enbrittle or discolour under the effect of the UV
radiation . If the lamp suffers damage ,the glass is contained in
teh shrunk on jacket.
Linear Lamps of any Size.
Circular and other shapes.
Fitted boots for U shaped lampes.
Low light transmission loss
Loss of UVA AND UVC light is much less compared with other polymer
coatings. For our usual coatings,loss of UVA is arround 4% and UVC
is 11%.We know of no other suitable flexible coatings that provide
less loss of UV.
Properties :
High low temperature resistance:
-200--260°C,high temperature strength is 2 times higher than PTFE
Good adhesive and heat sealability with PTFE:
Below melting point ,it won’t stick any project.Above melting point, it has perfect adhesive
property with PTFE, Metal and self-adhesion(heat sealing).
None stick to water ,oil :water contact angle:θ=1150o
Electric reliability,High dielectric
60HZ-60MHZ,Under the high and low temperature,thepermittivitykeeps2.1even if the surface damaged ,it won’t has conductive track.
Volume resistance>1018ΩM
Surface resistance>2*1013Ω
Voltaic Arc Resistance>165sNo electric leakageWeather resistance:It can be used in sunlight and ozone long
Anti-corrosion:Only in high temperature, Fluorin and alkalis can effect it,others
acid,alkali or ester won’t effect it.
Fireproof :If firing, and will still insulate .
High diaphaneity
UL-Resistance :Good penetrability in ultraviolet radiation,and lowest refraction
coefficient
