WEVOPUR

 

The filling characteristics of the resin components increase thermal conductivity, enabling designers to achieve optimal thermal management. Wevopur is also mechanically versatile with properties ranging from gel-like to elastomeric and impact-resistant to high dimensional stability. Clear, UV-stable systems are also available for transparent applications.

Main product features

  • Broad hardness range: Shore 00 to D 90
