POLLYCOTE-1550

POLLYCOTE 1550 is a pipeline anti-corrosion tape. Due to its excellent mechanical resistance it can be used also where a large diameter pipe is to be factory wrapped and transported to the installation site. The 1550, due to the use of an improved PVC backing, has a higher resistance to impact damage and penetration than POLLYCOTE 1500. It is designed for machine application and hand wrapping. POLLYCOTE 1550 has a tough PVC backing coated with a rubber modified adhesive.
