SEFAR PowerHeat – heating fabrics

The PowerHeat fabrics are woven fabrics usually consisting of 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

Energy efficient: high temperature/power ratio

Homogeneous surface temperature

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

Several kW/m2 heating power dissipation feasible when exposed
to liquids and composites

Light-weight (< 90 g/m2, filament diameters 40 – 80 μm)

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 mold processes

Can be pleated
