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

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

SEFAR PowerHeat used in heated head rest

SEFAR PowerHeat as insert in injection molds for automotive interior heating

Filtration industry

Screen basket having integrated heating


Heated operation blankets and mattresses

Home textile industry
