PE Liner (T-Lock & Plain)

Utilizing years of experience with polyethylene pipe extrusion, Union Pipes Industry LLC now manufactures PE Liner (T-Lock & Plain) as permanent protection for concrete pipes, other structures and applications. PE is the most chemically
resistant member of the polyolefn family on account of its dense configuration. Nowadays, it is the most commonly used membrane in various applications. It offers great ultraviolet protection and ageing resistance from the
severe stresses of weather and it is manufactured from the high-quality resins following a rigorous QA/QC program.
