    • 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
    • Adjustable flow properties
    • Filled and unfilled systems
    • Good temperature cycle behaviour
    • Clear, UV-resistant systems
    • Low dielectric constant
    • Self-extinguishing systems in accordance with UL 94 V-0
    • Good adhesion not only on conventional thermoplastics, but also on high-performance plastics such as LCP, BMC, etc.
    • Operating temperature range: -60 °C to +165 °C
    • Pot life adjustable from 1 to 90 minutes
    • Thermal conductivity up to 2.0 W/m·K
