Wood fibres for WPC

Only fibres from selected woods with clearly defined properties are suitable for WPC. The fibres should be of pure grade and have matching criteria, such as fixed grain sizes. This is the only way of adjusting biocomposites with defined properties, such as melting point and viscosity, to specific values.

We recommend JELUXYL for the manufacture of WPC. JELUXYL is of pure grade and guarantees the production of a homogeneous compound.

JELUXYL for WPC

Three different JELUXYL product categories are available to fulfil all requirements for manufacturing optimally adapted materials:

JELUXYL ® WEHO S
Fine flours made of spruce and fir wood

JELUXYL ® WEHO
Fibres and granulates made of spruce and fir wood

JELUXYL ® HAHO
Flours and granulates made of hardwood
