PTFE Coated Fabrics

Technical PTFE-coated fabric constructions selected for release, heat resistance and process stability, with material choice supported by datasheets, physical inspection and comparative testing.

MATERIAL CONSTRUCTIONS

Different weaves, coatings and thicknesses for different process duties.

The PTFE coated fabric family includes standard constructions, reinforced / tear-resistant solutions, anti-static materials and application-specific combinations. Final selection depends on thermal transfer, release behaviour, strength and machine conditions.

Standard PTFE coated fabricsGeneral-purpose release and heat-resistant constructions for process surfaces.

Tear-resistant constructionsReinforced material families where mechanical resistance is a key application requirement.

Anti-static fabricsConductive / anti-static variants for applications requiring controlled static behaviour.

Application-specific combinationsLayered or coated constructions qualified according to the required balance of heat transfer, release and durability.

COATED FABRIC RANGE

PTFE coated fabrics in standard, anti-static and application-specific constructions.

Representative roll formats include natural/brown, black anti-static and blue coated constructions, selected according to the required release, heat transfer, mechanical behaviour and process conditions.

CONTINUOUS PERFORATION PROCESSING

Continuous perforation of PTFE rolls up to 3500 mm × 50 m.

We can process PTFE coated materials with continuous perforation patterns on roll widths up to 3500 mm and roll lengths up to 50 linear metres, supporting application-specific airflow, release and process requirements.

Up to 3500 mm roll heightWide-format continuous processing for large technical fabric rolls.

Up to 50 linear metresContinuous roll processing without limiting the solution to short cut pieces.

Multiple perforation geometriesRound-hole, square-hole and open-mesh style patterns can be defined according to the process need.

Application-specific developmentHole size, pitch, material construction and open area are qualified from the real process requirement.

VERIFIED PERFORMANCE

We verify the material, not just the datasheet.

For LSC, technical quality is not a marketing claim. Material constructions are checked against real application behaviour, with technical data, comparative testing and physical inspection used to understand how thickness, weave, coatings and combined layers influence performance.

The smallest component should maximize the value of the entire production line.

A PTFE fabric may be a small part of the machine, but it must protect uptime, process stability and the value of the complete production line.

COMPARATIVE TEST RESULTS

Measured thermal transmission, side by side.

Maximum temperature recorded beneath each construction in the SEAL comparative test.

Source: SEAL comparative heat-transfer test. Temperature measured beneath each material during the controlled heating cycle.

Material	T max	What the report shows
15BLUE	118.7 °C	Highest heat transmission; linked in the report to lower thickness.
STD	110.8 °C	Second-best; the report points to its more open weave.
15SIL	108.9 °C	Good thermal transmission from the aluminium layer.
SIL	101.0 °C	About 5 °C above STV in the same period.
STV	95.7 °C	Lower transmission; associated with the tighter weave.
15BLUE + 15SIL	110.4 °C	Combination performs below 15BLUE alone.
STD + STV + SIL	94.6 °C	Lowest value; increased total thickness reduced heat transmission.

Thickness changes performance15BLUE reached 118.7 °C, the highest result measured.

Weave changes performanceSTD at 110.8 °C clearly outperformed tighter-weave STV at 95.7 °C.

More layers are not automatically betterSTD + STV + SIL reached only 94.6 °C.

Selection must be application-specificSimilar-looking PTFE constructions can behave very differently under heat.

HOW WE VERIFY

Technical data must be confirmed by behaviour.

SEAL testing documentation includes comparative heat-transfer trials on an HDF machine using vacuum and controlled heating, with thermocouples positioned under the materials and temperature acquisition recorded during the cycle.

Controlled heat-transfer testingMaterials were evaluated under vacuum and progressively heated up to 120 °C, with temperature measured beneath each sample.

Construction mattersThe test conclusions show that thickness and weave openness influence thermal transmission.

Combinations are validatedMulti-layer combinations were measured because adding layers can reduce heat transmission through increased total thickness.

Application before catalogueTechnical sheets are a starting point; final selection is qualified against machine geometry, duty cycle and the real process.
