Printashrink PF-A1 HW


Printashrink PF/A1 HW is a heavy walled heatshrink polyolefin with an integral thermoplastic adhesive liner. With a 3:1 shrink ratio, it has all the advantages of the standard PF/A1 3-1 and provides maximum reliability resistance for insulating and protecting joints and terminations. It is available in black as standard in sizes up to 350mm ID and can be cut and printed as required.

This glue lined, 110°C, heavy walled tube consists of a heatshrink polyolefin tube with a thermally activated inner adhesive liner. The inner liner melts and flows to encapsulate connectors and components providing moisture-resistant, environmental protection, strain relief and insulative properties which are perfect for high impact, abrasion, corrosion and chemical resistance. It is submersible and often used in direct burial installations. It is available in 1.2 metre lengths and with or without adhesive lining. We offer our full cutting and limited printing service on this specialist sleeve.
