Polymeric DOPO-based phosphorus PIN FR achieved UL94 v-0 (3.2 mm) in polyamide at 0.3% total phosphorus content. The phosphorus-nitrogen polymeric PIN FR was synthesised by melt polymerisation of a DOPO-derivative (DDP*) with DMDA** and caprolactam (a...
Theoretical analysis of how phosphorus PIN FRs effect aircraft carbon fibre – epoxy composites shows divergent conclusions. Two phosphorus PIN FRs were tested in carbon fibre high-temperature TGDDM epoxy (c. 33% fibre): a DOPO derivative* (16% loading) and a...
