PTFE PFA tube, PTFE PFA tubing,high temperature transparent tube
Introduction:
PFA 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 be solid
adhesive for PTFE and also a good adhesive for laminating various materials. Its working temperature is up 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 machine roll 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,the permittivity keeps 2.1 even if the surface
damaged ,it won’t has conductive track.
Volume resistance>1018ΩM
Surface resistance>2*1013Ω
Voltaic Arc Resistance >165s No electric leakage
Weather 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
