3M 5421 Polyethylene Tape
3M 5421 Polyethylene Tape is a tough and long lasting protective tape designed for demanding applications. This tape is produced from a ultra-high molecular weight polyethylene (UHMWPE) backing which is coated on one side with a rubberised adhesive. Finally, a strong and easy to remove densified Kraft paper liner is applied.
Manufactured by 3M, this high quality grade of tape exhibits the outstanding reliability, adhesion and high performance that this world leading manufacturer is known for.
3M 5421 Polyethylene Tape has an surface that exhibits outstanding resistance to abrasion and extreme wear. In many applications, the UHMWPE surface actually outlasts PTFE and other plastics known for their excellent sliding properties. It achieves this through its low coefficient of friction) which is exceeded only by PTFE’s) and the fact that it is self-lubricating which allows it to be used in applications where lubricants can’t be used for fear of contamination.
In addition to these performance characteristics, 3M 5421 Polyethylene Tape also offer high sounds damping performance which makes it ideal for reducing noise levels in and around loud machines and equipment.
This tough, strong and highly versatile product exhibits very good adhesion to steel (28 N / 100mm), tensile strength (526 N/100mm) and an elongation at break of 275%. 3M 5421 Polyethylene Tape has a total thickness of 0.17mm (without liner; without adhesive it is 0.13mm thick) and is translucent in colour (the backing is white as shown in the photo).
3M 5421 Polyethylene Tape is used in applications where temperature are between -34ºC and 107ºC.
Typical applications for this high quality, wear-resistant product include:
- Guide rails for conveyors
- Liners for spray booths
- Tank and bin liners
- Feed and grain chutes
- Discharge chutes
- Former noses
- Protecting aluminium sheets during forming
3M 5421 Polyethylene Tape is available from Associated Gaskets in a variety of different sizes and forms. Standard rolls are 16.4mtrs wide and can be slit by our in-house slitting facilities to whatever width is required for your application.
In addition to providing this quality wear resistant product in tape form, AG can also offer precision cut components. Our knife cutting and die cutting facilities are perfect for the quick and economical manufacture of custom sized components while our kiss cutting facilities mean we can also offer precision cut components that are still bonded to their original liner (and supplied in a roll). This option is perfect for anyone looking to repeatedly apply components made from 3M 5421 Polyethylene Tape as it minimises material waste, labour and potential for error.
In addition to the 0.17mm 3M 5421 Polyethylene Tape described here, AG is also pleased to offer the 0.3mm thick 3M 5423 Polyethylene Tape.
