Synergy between conventional phosphorus fire retardants and organically-modified clays can lead to fire retardancy of styrenics [PDF]

open access: yes, 2003
Polystyrene–clay nanocomposites combined with phosphorous-containing fire retardants have been prepared and used to explore the thermal stability and mechanical properties of the polymer formed. The amounts of fire retardants and clay used were varied to

Processing waste printed circuit boards for material recovery [PDF]

open access: yes, 2007
PURPOSE We have investigated the use of pyrolysis for the processing of waste printed circuit boards (PCBs). The aim was to make the process of separating the organic, metallic, and glass fibre fractions of PCBs much easier and therefore make ...

HET acid based oligoesters – TGA/FTIR studies [PDF]

open access: yes, 2008
One of the important reactive halogenated dicarboxylic acids used in the synthesis of flame retardant unsaturated polyester resins is 1,4,5,6,7,7-hexachlorobicyclo [2.2.1] hept-5-ene-2,3-dicarboxylic acid (HET acid).

Suitability and Modification of Different Renewable Materials as Feedstock for Sustainable Flame Retardants

open access: yesMolecules, 2020
Due to their chemical structure, conventional flame retardants are often toxic, barely biodegradable and consequently neither healthy nor environmentally friendly. Their use is therefore increasingly limited by regulations.

Preparation and properties of epoxy resin modified with phosphorus and nitrogen flame retardants

open access: yesMaterials Research Express, 2023
Epoxy resins (EPs) require the addition of flame retardants to extend their application scope. High-efficiency flame retardants typically contain halogens, which can cause tremendous harm to humans and the environment.

Quantification of polybrominated diphenylethers in oil produced by pyrolysis of flame retarded plastic [PDF]

open access: yes, 2008
In recent years, there has been extensive research into using pyrolysis to convert toxic brominated plastics into safe, bromine free fuels. However, there has been little investigation of the polybrominated diphenyl ethers (PBDE) that are present in ...
