DWP-125 Flexible, flame-retardant, adhesive-lined, polyolefin heat-shrinkable tubing Adhesive-lined, medium-wall industries such as appliance and As DWP-125 shrinks, the inner DWP-125 heat-shrinkable tubing is satellite communication. DWP-125 adhesive liner melts and flows to a versatile, environmentally friendly tubing has an outer jacket of seal and encapsulate components choice for many commercial radiation-crosslinked, flexible, or splices contained within. applications that require mechanical flame-retardant polyolefin. Because DWP-125 has a three-to- protection and sealing against Unlike other typical flame-retardant one shrink ratio, only a few sizes moisture and chemical ingress. tubings, DWP-125 tubing is free of are needed to cover a wide range of polybrominated biphenyls (PBBs) substrate diameters, enhancing Typical applications include and polybrominated biphenyl oxides inventory efficiency. DWP-125 is environmental sealing and protection (PBBOs).
