PTFE Adhesive Tape 0.08mm TEFSIL® 3

SKU: 620947465580

Also known as Teflon ® tape, Tefsil 3 Adhesive is a PTFE coated glass cloth tape with a heat resistant silicone adhesive applied to one surface. The adhesive will operate up to 260°C and can be thermoset at 200°C for 4 hours. Tefsil 3 Adhesive is a very popular tape with OEM’s as it offers an affordable but effective release media for heat sealers, L-Sealers and flow wrappers. If you cannot see the width you require please give us a call on 0044 (0) 1422 366386 as we slit to any width from 10mm up to 1000mm wide.

Supplied in 30 metre rolls - please select width

Material Properties
• Extremes of heat and cold resistance: -73°C to + 260°C • Chemical inertness: Affected only by a few rare substances at very high temperatures
• High Release from sticky materials 'Non-Stick' • Easy cleaning (nothing bonds permanently)
• Low friction co-effecient: 0.04 - 0.10; depending on load and surface speed • Chemical corrosion and moisture resistance
• Mildew and fungus resistance • Ultra-Violet, Infra-Red, Micro-Wave, Radio Frequency resistance
• Non Combustible - Self Extinguishing • Low Thermal Expansion: < 5%
• Food Approval (USFDA) • Lightweight and energy efficient for economical operation
Additional Information
Availability: PTFE adhesive tape is available ex stock and can be supplied at any width from 3mm up to 2600mm wide.
Fabric Care: Do not fold or crease when handling and installing. The fabric can eventually discolour in sunlight (turns white), but otherwise is unaffected by biological or chemical agents, heat or cold within its temperature range, or by most areas of the electric magnetic spectrum.
The material can be converted to engineering product. Consult our Technical staff for further details. Also available chemically etched one side for proprietary adhesive bonding. Standard etch is silica based, sodium based etch is available on request.
PTFE (Teflon) begins to soften at 260°C, increasing in wear rate, Somewhat above 300°C fumes are given off and these should not be inhaled. COSHH data is available upon request.

Important Storage / Shelf Life and Application Information
• Storage:
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.
• Surfaces:
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.
• Cleaning:
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.
