  pages={25 - 40}
The review covers materials currently available or which appear to be in serious development, with emphasis on electrical laminates and encapsulation, and brief coverage of other applications. The dominant technology for FR-4 printed wiring boards uses tetrabromobisphenol-A reacted into the epoxy resin. Nonhalogen systems include additives such as alumina trihydrate, alumina trihydrate plus red phosphorus, and aromatic phosphates. Reactives include a dihydrooxaphosphaphenanthrene oxide and… 
Recent Developments in Halogen Free Flame Retardants for Epoxy Resins for Electrical and Electronic Applications
This review will discuss the latest advancements in phosphorus containing flame retardants for electrical and electronic (EE) applications and compare them with commercially available ones.
Flame retardants for epoxy resins: Application‐related challenges and solutions
Owing to their high versatility from chemical and processing perspectives and hence their capability of being tailored for required properties, epoxy resins are used in a wide range of applications
Role of Copper Oxide on Epoxy Coatings with New Intumescent Polymer-Based Fire Retardant
A positive influence of CuO on the epoxy-headed intumescent flame retardant coatings is demonstrated and it is shown that CuO can enrich the power and compression of the intumecent char that restricts the movement of heat and oxygen.
New star-shaped phosphorus-containing flame retardants based on acrylates for epoxy resins
New star-shaped phosphorus-containing flame retardants were synthesized by phospha-Michael-addition of diphenylphosphine oxide and dimethyl phosphite to oligofunctional acrylates. The products were

Synthesis and properties of flame‐retardant epoxy resins based on DOPO and one of its analog DPPO
Two phosphorus-containing heterocyclic flame retardants -9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and 2,8-dimethyl-phenoxaphosphin-10-oxide (DPPO) - and their derivatives were
Flame retardant epoxy resin based on bisphenol A epoxy resin modified by phosphoric acid
Flame retardant epoxy resin (FREP) were synthesized from phosphoric acid and bisphenol A epoxy resin (BAEP). The structure of the FREP was characterized using FTIR and 31P NMR. Then, several
Flame retardant epoxy resin for electrical and electronic applications
Amine‐cured epoxy resins were prepared at 2% by weight phosphorus content using four halogen‐free flame retardants; poly(m‐phenylene methyl phosphonate) (Fyrol PMP);
