Sealing strip with improved resistance against hydrocarbon(s) - comprises plastic strip sprayed with very thin layer of polyester

摘要

A plastic sealing strip is described which has an applied polyester layer for improved resistance against aggressive materials. The layer has a thickness of only 0.1 mm and can be sprayed on to the plastic sealing strip. A layer can be applied over two overlapping strips or can form an intermediate layer (13,14) between the sealing strips (10,11,12) and a weldable outer layer (15,16,17). USE/ADVANTAGE - For sealing against materials which are more aggressive than water e.g. hydrocarbons.
