Wevo’s new silicone-based materials inhibit thermal runaway
Wevo-Chemie has developed a range of silicone-based materials for battery modules and packs to prevent thermal runaway propagation. The thermally conductive gap fillers of the WEVOSIL 260XX FL series are certified UL 94 V-0. The company says its formulation has high heat and flame resistance, lower weight compared to mineral or metal-loaded compounds, and no outgassing… Read more »
Wevo potting compounds used in supercapacitors
WIMA, a maker of film capacitors, employs Wevo potting compounds in its supercapacitor PowerBlock—a cascaded, double-layer capacitor module whose capacitance, rated voltage and dimensions can be individually adapted to a desired application. This allows a range of mobility applications, such as engine starter modules in large construction and agricultural machinery, ships, locomotives, trams and buses,… Read more »
Wevo’s temperature-resistant materials designed for EV electrical components earn UL ratings
Wevo, a maker of potting, bonding and sealing compounds, has earned UL RTI (Relative Temperature Index) approval for several of its flame-retardant polyurethanes, and one temperature-resistant epoxy resin has been certified to UL 94 V-0. RTI certification refers to long-term temperature resistance. In the case of polyurethanes, this is usually a maximum of 130° C…. Read more »
