Abstract
A self adhesion ensuring layer having a total thickness of 0.05 to 0.2 mm is carried on a PVC-foil carrier sheet having a thickness of 0.2 to 0.5 mm. The self adhesion ensuring layer comprises 70 to 100% by weight of synthetic caoutchouc, 0 to 16% by weight bitumin and 0 to 14% by weight talc. A ground layer may be interposed between the carrier sheet and self adhesion ensuring layer. The resultant system is useful for insulation of underground pipe.
