SM270 Daflex Shrink/Melt Irradiated Polyolefin Tubing
Daflex Shrink/Melt Irradiated Polyolefin Tubing
Shrink Ratio 3:1
MIL-I-23053/4 Class 3†† - UL 105°C
Description: Daburn's dual wall polyolefin heat shrinkable tubing is designed to provide a tight
moisture proof encapsulating seal. When 110°C/230°F is applied, the inner wall melts and flows, as the
outer wall shrinks; forcing the melting wall to fill voids and interstices and to encapsulate the covered
object. The result is a semi-rigid mass.
It is suitable as an end cap, strain relief, whip cord for ropes and may be used as a selective potting and/
or molding compound over wires and cables.
Daflex SM270 series is ideal for covering splices, cable junctions and as a shield for coarse surfaces.
SM270 is flame retardant. It resists oil, hydraulic fluids, acids and alkalis.
Meets or exceeds Mil-I-23053/4††, AMS3634, UL 224: 125°C, 600V, VW-1.
This series is RoHS compliant.
