Welcome to Printasleeve - High Quality Printed Sleeving Products for All Your Professional Needs

PTFE TW

PTFE TW (Polytetrafluoroethylene) is a non-flammable, thin-wall sleeving with an exceptionally high operating temperature of -70°C-+260°C. It has a very low coefficient of friction, high dielectric strength and is virtually inert to all chemicals. It is available in many colours and AWG, metric and imperial sizes as standard. Bespoke sizes, wall thicknesses and colours are also available.

PTFE hose and convoluted tubing is ideal for enhanced protection of wire, cable, electrical and electronic components for commercial and high performance military and aerospace systems. It is extremely stable at very high temperatures and retains a measure of toughness and strength even at cryogenic temperatures. It is virtually inert to all chemicals resisting most acids. Alkalis and petroleum products. It is virtually unaffected by oxygen, ozone and UV light. It is extremely hydrophobic and has a UL 94 rating of V-O. It also has a very low co-efficient of friction and high dielectric strength and excellent mechanical properties.

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.
