FEP heat shrink tubing made of perfluorinated propylene material, which has excellent transparency and temperature resistance. It still has excellent shrinkage at high temperatures, and after shrinkage, the surface appears bright without defects, mainly used in medical instruments such as surgical instruments, catheters, and microcatheters.
◎ Shrinkage ratio: 1.3:1, 1.6:1.
◎ Operating temperature: -65 ° C to 200 ° C
◎ Shrinkage temperature: 200 ℃~230 ℃, Excellent electrical insulation performance and physical inertness
◎ Compliant with ISO 10993-1
◎ Full epoxy ethane (ET0), gamma sterilization
◎ Environmental standards: compliant with RoHS
Standard color: transparent

FEP heat shrink tubes are manufactured from pure high-molecular FEP tubes (Fluorinated ethylene propylene) to provide them with an extraordinary stretching behavior and a long life-time.
FEP is part of the fluoropolymers and offers properties such as a high UV stability, best possible anti-adhesive behavior on a particular smooth surface, a wide range of temperatures of use and a nearly universal stability against acids and bases. The shrinking temperature is about +180°C +/- 10°C. (356°F +/-15°F)
Properties FEP heat shrink
Very good anti-adhesive properties (no adherence)
Highly transparent
Easy to apply
Long-lasting at continuous temperatures up to + 205 °C (+ 400 °F)
Safe for food and beverages
UV-stable
Labs-free (free of parasitical painting moistening substances)
Easier and faster to apply than PTFE heat shrink tubes
