SKY M23053/8 - M23053/18 Class 1

KYNAR* TUBING 
2:1 MINIMUM SHRINK RATIO
175°C Operating Temperature 
DESCRIPTION:

WEICO's Kynar is an irradiated, thin-wall, heat-shrinkable tubing
offering a high degree of mechanical strength and high temperature
resistance. When heated in excess of 175°C, it will shrink to fifty
percent of its supplied diameter. Fabricated from polyvinylidene
fluoride, the tubing has outstanding abrasion resistant and cut-through
properties in combination with high dielectric strength. Kynar tubings
are recommended for shrink-fit protection and strain relief of wires,
solder joints, terminals and connections. Suggested applications
include automotive wiring, jackets, fuse coverings and military wire
markers. Because the tubing is transparent, it affords see-through
inspection and identification when used as jacketing for components
such as resistors and capacitors. It is semi-rigid and highly resistant
to most industrial fuels, chemical and solvents. Kynar tubings are readily
marked by hot-stamp and print-wheel equipment.

CHARACTERISTICS:

SKY Kynar tubing has a 2:1 shrink ratio. When freely recovered, the
tubing will shrink to 50% of its supplied diameter. SKY tubing meets
MIL-I-23053/8, MIL-I-23053/18, Class 1 and AMS-3632. SKY tubing
is rated for continuous operation from -55°C to+175°C.
