Printashrink PF/A1 3-1

Printashrink PF/A1 3-1 is a 3:1 shrink ratio, dual wall heatshrink polyolefin with an integral thermoplastic adhesive liner. It provides encapsulation of inner components, environmental sealing and moisture-resistant insulation, and is available in black and clear as standard in sizes up to 40mm ID. It can be cut and printed as required.

This glue lined, 110°C, general purpose tube consists of a flame retarded heatshrink polyolefin tube with a thermally activated inner adhesive liner. The inner liner melts and flows to encapsulate connectors and components providing a moisture-resistant, environmentally protective, permanent seal. It is used in a vast number of applications, one of the most popular being connector to cable transitions. It is available in 1.2 metre lengths or on reels, and can be supplied with UL approval. We offer a range of printing and cutting services on this high strength, resilient tube also making it perfect for identification, branding and marking requirements.
