RJS-E
Wrap‑around heat‑shrink sleeve for sealing the joint casings of pre‑insulated district heating pipes. A cross‑linked HDPE backing (PE‑X) and a dual adhesive: a high‑shear hot‑melt at the edges anchors the sleeve against ground movement, and a visco‑elastic sealant in the centre forms the actual moisture seal. A dimpled Permanent Change Indicator on the backing disappears once the correct shrink temperature is reached, so a finished joint can be inspected afterwards.
