AQUATHENE CM 92949 is a black masterbatch designed for use with AQUATHENE AQ 120-000 ethylene vinylsilane copolymer for producing low voltage, power cable insulation. When CM 92949 is added at 9 wt % to AQ 120-000 and the appropriate catalyst masterbatch such as AQUATHENE CM 04482, the resulting material is suitable for use in applications such as USE and USE-2 cable. The compound is crosslinked by exposure to moisture.
