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.

Typical applications include

environmental sealing and protection

of irregular shapes, such as wire

splices and break-outs, in demanding

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.

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-to-

one 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.
