	SPECIAL RECOMMENDATIONS

Special Recommendations

PTFE has a strong tendency to creep and is unable to sustain constant high load. Creep may occur during thermal cycling. · All PTFE-insulated wires and cables tested up to now have been found acceptable for space use. · PTFE is rather sensitive to radiation and its use outside a spacecraft, particularly in high-radiation zones (Van Allen belts, geostationary orbit) requires special testing. · Volume change associated with a change of crystallinity occurs between approx. 22 to 27°C.
