Printashrink PF/A1 MW

Printashrink PF/A1 MW is a medium 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, but provides a greater resistance to abrasion and chemicals. It is available in black as standard in sizes up to 200mm ID and can be cut and printed as required.

This glue lined, 110°C, medium 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 perfect for low voltage electrical and mechanical applications where a degree of flexibility is important. 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.
