SFL 4:1 SHRINK RATIO - ADHESIVE LINED - M23053/4

POLYOLEFIN TUBING
4:1 SHRINK RATIO
110°C Operating Temperature 
DESCRIPTION:

WEICO's SFL series is a medium-wall, semi-rigid tubing lined with
a layer of special thermoplastic adhesive. When heated in excess
of 121°C, SFL tubing shrinks and conforms to the unit to be covered,
while the inner wall of adhesive melts and flows to provide a moisture
and corrosion 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 SFL multiple wall tubing is ideally suited for applications where moisture
protection of wire splices or bundling of wires is required.

CHARACTERISTICS:

SFL Polyolefin tubing has a 4:1 shrink ratio. When freely recovered, the tubing will
shrink to 25% of its supplied diameter. STL tubing is rated for continuous operation
from -55°C to +110°C.
