Descripción general

Phenylbis(2,4,6-trimethylbenzoyl) phosphineoxide (BAPO) is potential photoinitiator widely used in the preparation ofdental composites.

Aplicación

Phenylbis(2,4,6-trimethylbenzoyl) phosphine oxide can be used as a photoinitiator for:
  • Radical polymerization of dental resins. BAPO enhances the polymerization rate and conversion compared to other initiators.
  • Preparation of divinylbenzene modified polymer-based ceramic materials for high temperature sensor applications.
