BURGESS CB - Technical Data Sheet
BURGESS CB
SURFACE MODIFIED CALCINED ALUMINUM SILICATE
BURGESS CB has been designed for use in EPR, EPT, crosslinked polyethylene, and polyester. It yields excellent dispersion in these systems with minimum work. CB gives excellent wet and dry electricals by means of lower water vapor transmission.
BURGESS CB allows for higher filler loading in polyester bulk and sheet molding compounds and clay filled epoxies due to reduced viscosity. Better dispersion through easier polymer wetting of the filler is another advantage obtained with Burgess CB clay.
