The electrical properties of CALIBRE*
polycarbonate resins make them desirable for electrical
and electronic applications. Their excellent electrical
insulation properties are complemented by transparency and
mechanical strength over a wide temperature range - a combination
not found in most other thermoplastics. Further, with CALIBRE
resins, these electrical properties are not significantly
affected by moisture or by the melt flow rate of the resin.
Basic electrical properties for CALIBRE polycarbonate
resins are shown in following table.
