1. FEPWhat is heat shrink tubing?
Perfluoroethylene Propylene(F46, FEP) heat shrinkable tubing.FEPHeat shrinkable tubing is usually a relatively thin type of tube that can be shrunk.FEPThe thinnest heat shrinkable tube has
0.1mm, the thickest is 2mm, usually seen thin-walled heat shrinkable tube impression: very light, very thin, poor compressive performance, thin and light isFEPheat shrinkable tube
Key features.FEP, like other meltable fluoroplastics, is hot-molded, die-cast, and extruded (vacuum and air pressure molding) using common methods. In the standard
In the quasi-equipment, all molded parts in contact with molten fluoroplastics should be made of corrosion-resistant alloys.

3.Color of FEP Heat Shrinkable Tubes
Commonly used color: transparent, black;
Not commonly used color: yellow, brown, green, blue and other colors can be customized.
Characteristics of 4. FEP Heat Shrinkable Tubes
Common features:
Use temperature:-200Degree200Degree
Easy processing: can flanging, welding
Aging resistance: can be exposed to ozone and sunlight for a long time without aging
High transparency: in all plasticsrefractive indexLow, can be very intuitive to see the flow of the medium in the tube
Corrosion resistance: able to withstand in addition to moltenalkali metal, fluorinated media as well as higher300°of all strong acids, strong oxidants, strong reductants
and variousorganic solventThe role
Infrequently used features:
Density:2.14-2.17g/cm3
Volume resistance>1 × 1018
surface resistance>>2 × 1013
Arc resistant>165Seconds without leakage
Low water absorption: water absorption <0.1%
Lower coefficient of friction: smaller coefficient of friction
Surface non-stick: known solid material head can not adhere to the surface
Incombustible: the air will not burn, in line with the strict requirements of the fire place
Non-toxic: five toxic tasteless, with physiological inertia, no harm to people and the environment
