An overview of some recent advances in DOPO-derivatives
These DOPO-derivatives are used as flame retardants mainly in epoxy resins [3], [5], [11], [12], [13], [15], for applications in adhesives, composites, printed wiring boards and others [17]. As some halogenated flame retardants have been found to be toxic, the research on halogen-free flame retardants is gaining more and more importance [18].
Flame retardant effect and mechanism of a novel DOPO based
All these compounds revealed high flame retardant efficiency for epoxy resin due to the synergistic effect between DOPO group and nitrogen-containing heterocycle. Yang et al. reported a novel flame retardant containing DOPO and maleimide groups [20]. The synergistic interaction of functional groups imparted excellent flame retardancy to epoxy
Flame retardant Plamtar-DOPO-HQ - Polymate Additives
Plamtar-DOPO-HQ is a new phosphine halogen-free Flame retardant, for high quality epoxy resin such as PCB, to replace TBBA, or adhesive for semiconductor, PCB, LED and so on. Intermediate for synthesis of reactive Flame retardant. Packing. 25kg/bag.
Synthesis of a novel flame retardant based on DOPO
An intumescent flame retardant (DOPO-DAM) containing phosphorus and nitrogen was synthesized via a two-step process and then, it was incorporated into waterborne polyurethane to serve as a reactive flame retardant for preparing flame-retarded WPU (FR-WPU). The chemical structures of DOPO-DAM and FR-WPU were confirm
Bi-DOPO Structure Flame Retardants with or without Reactive
A novel reactive phosphorus-containing flame retardant 1,4-phenylene-bis((6-oxido-6H-dibenz[c,e][1,2]-oxaphosphorinyl) methylene) diacrylate (TDCAA-DOPO), with two symmetrical 9,10-dihydro-9-oxa-10-phosphaphena-nthrene-10-oxide structure (bi-DOPO), was synthesized and combined with unsaturated polyester resin (UPR) via cross-linking to prepare flame-retardant UPR (FR-UPR). To make clear both
