Printashrink PTFE 4-1

Printashrink PTFE 4-1 is a heatshrinkable sleeving with exceptional resistance to chemicals, solvents and high temperatures. It has a continuous operating temperature of up to 250°C, a 4:1 shrink ratio as well as high electrical and total UV resistance. It is available in transparent in sizes up to 50.8mm ID and can be cut as required.

This equivalent to Teflon® which has an operating temperature of up to 250°C, offers exceptional resistance to virtually all fuels, chemicals and solvents, and is non-flammable. It is suitable for use in many applications where its unique properties are used to solve problems other materials are unable to including aircraft, medical and chemically hostile environments. We offer a range of cutting services on this tube.
