Description ATUM

ATUM is a 4:1 shrink ratio, general purpose, flexible, polyolefin tubing with a thermoplastic adhesive inner liner. The inner liner will melt and flow to environmentally seal and protect components and interconnections.

The Raychem brand of heat shrinkable sleeving (now owned by TE Connectivity) is world renowned as the market-leading product. ATUM 4:1 is supplied with the optimum amount of adhesive to ensure that the product fully seals. After a successful installation one should see some excess adhesive wicking from the tube.  This is a telltale sign that the product has a complete seal. There are many cheaper and inferior products available, but none of these has the same amount of adhesive or performs to the same level.

Undoubtedly, this product is ‘The King’ of the adhesive lined heat shrink products.
