• Reactive DOPO derivatives do not leach during fire use in epoxy products. exhibit dual gas and condensed phase activity. Self–extinguishing smoke suppression are exhibited via aromatic hardeners. Epoxy resins widely applied industry for producing safe materials. Unfortunately, have the disadvantage of being highly flammable thus require suitable modifications with reactive or non-reactive fla...

Abstract We investigated the industrial applicability of multifunctional flame-retardant epoxy gelcoats based on flame retardants containing phosphorus (P), in particular ammonium polyphosphate (APP, which acts solid phase), resorcinol bis(diphenyl phosphate) (RDP, mainly gas phase) and their combination. It was possible to apply most formulations via spraying with use a diluent, while RDP were...

Polyvinyl alcohol- (PVA-) based aerogels have attracted widespread attention owing to their low cost, eco-friendliness, and density. However, the applications of PVA-based are limited by flammability. In this study, a flame retardant, ammonium polyphosphate (APP), biopolymer, chitosan (CS), were added polyvinyl alcohol (PVA), polymer was further crosslinked using boric acid (H3BO3). PVA aerogel...

In this research, low-melting phosphate (LMP) glasses (G1, G2, G3) were employed as green flame-retardant synergist additives in epoxy (EP)/ammonium polyphosphate (APP) composite. To investigate their performance additives, comprehensive fire tests and characterizations carried out, including limiting oxygen index test, UL-94 vertical burning cone calorimeter real-time temperature detection, X-...

This study synthesized and investigated the efficacy of a novel flame retardant, melamine formaldehyde microencapsulated piperazine pyrophosphate (MFPAPP), in improving thermal flame-retardant properties thermoplastic polyurethane (TPU). When TPU was incorporated with 30wt% MFPAPP, limiting oxygen index (LOI) value TPU/MFPAPP composite increased to 38.8%, achieving V-0 rating. The thermogravime...

The selected functional properties of rice husk/wood blended particleboards which include thermal analysis, limiting oxygen index, morphological and mechanical have been investigated. Rice were produced with one step hot press casting technique using citric acid to improve the compatibility in calcium oxide aluminum as flame retardants. results showed improvement properties, retardancy, stabili...
