SEFAR PowerHeat – heating fabrics

The PowerHeat fabrics are woven fabrics usually consisting of wires, PET and electrically conductive filaments. PowerHeat has the following properties:

Customer-specific designs

Quick heating up due to low intrinsic mass

No hotspots

Electrically insulated or not insulated

Energy efficient: high temperature/power ratio

Homogeneous surface temperature

Up to 1000 W/m² heating power dissipation when exposed to air

About 10 – 20 kW/m² heating power dissipation feasible when exposed
to liquids and composites

Light-weight (< 90 g/m²)

High air permeability (> 8000 l/m²/s, depending on fabric design)

Soft: can be placed closely to surface that needs to be heated up

Compatible with injection / back-injection mold processes

Can be pleated

3D-shaping capability

Very quick heating-up curve

Homogeneous temperature distribution at surface

3D shaped heating fabric after thermoforming process

Examples of applications with imbedded PowerHeat fabrics

Automotive industry
