1. Coffee PTFE Tape Overview
PTFE Coated Fiberglass Telfon Tape is a coffee-coloured PTFE tape with silicone adhesive, offered in two documented gauges. It is intended for hot sealing, roller protection and electrical insulation.
2. Two Gauge Test Comparison
| Test item | 0.08 mm grade | 0.13 mm grade |
|---|---|---|
| Thickness tolerance text | 0.01–0.015 mm | 0.02–0.03 mm |
| Wear coefficient | 10.3 | 13.8 |
| Elongation | 5% | 5% |
| Voltage resistance | 3 kV | 5 kV |
| Steel adhesion text | 16 N/100 mm | 18 N/100 mm |
| Extension strength text | 1500 N/100 mm | 2500 N/100 mm |
Heat resistance is described as 250–300°C, and normal-temperature warranty is one year.
3. Insulating Non Stick Layer
The coated face reduces sticking and isolates the machine surface, while fiberglass provides handling strength. The thicker grade carries the higher listed voltage and extension values.
4. Roller And Heat Seal Uses
Published work covers food, dairy and medicine packaging, plastic-film sealing, dye or resin processing rollers, laminating coaters and insulating encapsulation.
5. Telfon Tape Placement
Choose the gauge from electrical and mechanical requirements, clean the machine contact area and apply the coffee tape under uniform pressure. Avoid creases across a heated product path.
6. Electrical Test Checks
Confirm the unusual thickness-tolerance wording with the supplier, then verify wear value, voltage test, steel adhesion and heat exposure. The source units contain spelling errors and need a formal datasheet.
7. Silicone Roll Conversion
Silicone-coated conversions can be planned after gauge and roll geometry are approved. State heated-zone width, voltage requirement, temperature cycle and replacement interval.
8. Coated Fiberglass FAQ
Which grade has the 5 kV statement? The 0.13 mm version.
Is the 250–300°C range fully conditioned? No duration is shown, so request test details.
Why clarify tolerance? The legacy numbers do not read like ordinary finished-gauge tolerances.
Equipment buyers benefit from tying coffee-coloured PTFE tape to a documented electrical grade.
