Product Overview
4,4'-Difluorobenzophenone is the core monomer for polyetheretherketone (PEEK). Its nucleophilic substitution polycondensation with hydroquinone directly governs the molecular weight distribution and end-group stability of the resin. Yuanzhen Materials combines multi-stage distillation with directional crystallization, keeping batch-to-batch purity variation below 0.1%.
Beyond high-performance polymers, the product serves as a fluorinated pharmaceutical intermediate and an arylation reagent for API and crop-protection manufacturers. Custom particle sizes (powder or flakes) and tonnage supply programs are available on request.
