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.

Continuous Flow Manufacturing for Monomer Synthesis

The manufacture of monomers for use in ophthalmic applications is driven by the need for higher purity, improved reliability of manufacturing supply, but ultimately by the need for the increased comfort, convenience, and safety of contact lens wearers. Daily wear contact lenses have the potential to fill this need for many customers; however, their widespread use is constrained by higher costs compared to weekly- or monthly-based lenses. New approaches that improve cost structure and result in higher quality raw materials are needed to help make contact lenses more affordable and accelerate growth of the contact lens market.
