STL 3:1 SHRINK RATIO - ADHESIVE LINED - M23053/4 Class 3

POLYOLEFIN TUBING
3:1 SHRINK RATIO
110°C Operating Temperature
DESCRIPTION:

WEICO's STL tubing is a flame retardant, flexible polyolefin lined
with a layer of special thermoplastic adhesive. When heated in excess
of 121°C, STL tubing shrinks and conforms to the unit to be covered,
while the inner wall of adhesive melts and flows to provide a moisture
and corroson resistant seal. The adhesive forms a flexible bond with a
wide variety of rubbers, plastics and metals. Upon cooling, the adhesive
solidifies, forming a permanent, non-drying, flexible and waterproof barrier.
The STL multiple wall tubing is ideally suited for applications where moisture
protection of wire splices or bundling of wires is required.

CHARACTERISTICS:

STL Polyolefin tubing has a 3:1 shrink ratio. When freely recovered, the tubing will
shrink to 33% of its supplied diameter. STL tubing meets MIL-I-23053/4 class 3.
STL tubing is rated for continuous operation from -55°C to +110°C.
