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.

Free Artwork Service

As part of the fully comprehensive print process, we offer a free artwork service for both thermal and hot foil printing. This involves, advising on print suitability, resizing to fit final fitted size and re-ordering information supplied in spreadsheet format according to the sequence of installation or into kits.

To ensure superior print results, it stands to reason that artwork needs to be best quality and this is why we advise on whether artwork is suitable for purpose in terms of fine detail and ornate graphics which may not successfully transfer to smaller sleeves and markers, or where a high shrink rate is required. Furthermore, as heatshrinkable products do not shrink in a uniform manner (transverse and longitudinal shrink ratios differ widely) we resize artwork so that there is a strict correlation between original and final fitted dimensions.

We accept many formats for artwork including, but not limited to, tiff, eps, bmp, jpg, gif and PDF. For jpeg, save your image using the best quality. We use a single colour print system. This means the sleeving and print can be different colours, but the print itself can only be one colour. For best results send your image in black and white with what you would like printed in black. We can then take the image and print it on your selected sleeving in the correct print colour.

We also print from spreadsheets, CSV or text files, .lists or drawings. Where required, we can sort, print and pack according to the sequence of installation.
