DWP-125
Flexible, flame-retardant, adhesive-lined,
polyolefin heat-shrinkable tubing
Adhesive-lined, medium-wall
DWP-125 heat-shrinkable tubing is
a versatile, environmentally friendly
choice for many commercial
applications that require mechanical
protection and sealing against
moisture and chemical ingress.
industries such as appliance and
satellite communication. DWP-125
tubing has an outer jacket of
radiation-crosslinked, flexible,
flame-retardant polyolefin.
Unlike other typical flame-retardant
tubings, DWP-125 tubing is free of
polybrominated biphenyls (PBBs)
and polybrominated biphenyl oxides
(PBBOs). In Europe, these chemicals
are classified as environmentally
hazardous substances.
Typical applications include
environmental sealing and protection
of irregular shapes, such as wire
splices and break-outs, in demanding
As DWP-125 shrinks, the inner
adhesive liner melts and flows to
seal and encapsulate components
or splices contained within.
Because DWP-125 has a three-toone shrink ratio, only a few sizes
are needed to cover a wide range of
substrate diameters, enhancing
inventory efficiency. DWP-125 is
UL-recognized and CSA-certified at
125°C, 600 V.
