Flame retardance and smoke suppression mechanisms of triphenyl phosphate (TPP) and zinc stannate(ZS) alone and together in the anhydride cured epoxy resin(EP) were studied by limited oxygen index(LOI), thermogravimetry analysis(TGA) and NBS techniques.

Thermal conductivities of cured epoxy resins commonly used to make electrical insulating materials were mensurated by guarded heat flow meter technique,and the influences of cured resin structure on its thermal conductivity were discussed in this paper.

The latent curing acceleration of the rareearth organometallic compound (MrAn) for the anhydride/epoxy resin system was studied by DSC, TG and rotation viscometer, etc.
