Dual thin wall heatshrink polyolefin, medium wall & heavy wall

The term DUAL WALL means

A double insulation environmental sealing component, an outer walled material of cross linked polyolefin, supplied with an inner wall extrusion of A adhesive (glue) and/or M mastic lining which produces an environmental seal. It comes in many characteristics, either thin wall, medium wall or heavy ((3:1, 4:1 or even 6:1 shrink ratio supplying more scope for insulation of Thick)) walled, your components.

Single wall heat shrinks will provide certain protection of components, but dual walled materials provides sustained environmental sealing for your application. If you require temperatures of up to +200°C then please do contact us as we have a solution.

These heat shrinkable tubings provide superb environmental protection. Moisture-proof products that are ideal for protecting cable splices, electrical, electro and mechanical components that are exposed to the elements. These products have a high expansion ratio which allows components to be sealed directly to cables and wires, except for our EDW 2 which will fill voids, but will not bond direct to substrates, cables
or metal substrates, it is a void filler only. As the various products are heated to their respective correct shrink temperatures, the tubings begins to shrink down to their recovered thermal memory parameters, the adhesive lining will flow to seal and encapsulate electrical/electronic components or splices
contained within, thus producing a superb excellent water tight environmental seal.
