|Areas of use include mechanical applications such as electrical insulation and cable wrapping, bellows and hose liners, gaskets, tank and vessel lining, slide bearings, skid ways, pipe supportand bearing tape. They are also used in many other applications requiring high temperature resistance, low friction and a non-stick surface use on extrusion lines where rubbers, plastics or sticky products may stick to other belt surfaces.|
|Features & Benefits|
|Skived PTFE tape is not supported by woven fiberglass as other PTFE adhesive tape is and therefore offer excellent conformability in to radiuses and other areas where PTFE coated glass cloth tapes are not suitable. Due to the skived PTFE not being supported by a carrier it has an extended life over standard PTFE glass cloth tapes (often incorrectly referred to as Teflon®) and is therefore more suited to environments that may produce a high wear rate.|
Skived PTFE tapes come in four different grades ranging from 0.08mm to 0.50mm thick. all have a high temperature resistant, silicone adhesive backing. The adhesive is pressure sensitive and will adhere to hot metal surfaces. They are supplied in slit roll form ranging from 10mm to 1000mm wide an 30mtr coils. We also sell these products by the square meter. Lead time is generally same day dispatch from order.

|Important Storage / Shelf Life and Application Information|
We strongly recommend that Techbelt silicone PSA tapes are stored at room temperature conditions of 21⁰C (70⁰F) and 50% relative humidity and should be protected from direct sunlight and moisture.
|• Shelf Life:|
If stored correctly, these products retain their performance and properties for 6 months from date of manufacture.
The surfaces of the materials to be bonded must be dry and clean. Condensation of moisture on surfaces to be bonded (e. g. when carrying cold objects into a warmer room) must be avoided. The materials to be bonded must be free from dust, grease, oil and separating agents and cleaned if necessary.
For cleaning the surfaces only use a clean cloth and a solvent that is compatible with the materials, e. g. benzines, alcohol, esters or ketones.
