چکیده

The recent implementation of new environmental legislations led to a change in the manufacturing of composites that has repercussions on printed wiring boards (PWB). This in turn led to alternate processing methods (e.g., lead-free soldering), which affected the required physical and chemical properties of the additives used to impart flame retardancy. 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. The mechanism of degradation and flame retardancy of phosphorus flame retardants in epoxy resins will also be discussed.

A Novel Non-Halogenated Flame Retardant for Composite Materials

Flame retardants, such as inorganic fillers or halogenated resins, are incorporated into composites either as additives or reactive materials. In order to improve processability and mechanical properties, as well as reduce smoke toxicity, a method is being developed to introduce highly effective, inexpensive flame retardant materials into thermoset resins. Superabsorbent polymers (SAP) can be l...

Leaching of halogen-free and brominated flame retardants from polymers - Influence of leaching parameters Submitted to Journal of Hazardous Materials

The ban and restrictions on some of the brominated flame retardants (BFRs) has led to an increase in use and production of alternatives such as halogenated free flame retardants (HFFRs). Limited information is available on the occurrence and fate of inorganic HFFRs. Inorganic HFFRs such as aluminum polyphosphinate (AlPi), melamine polyphosphate (MPP) and zincstannate (ZS), dissociate into ions ...

Synthesis of a Novel Phosphorus-containing Flame Retardant for Epoxy Resins

In this study, a novel phosphorus-containing flame retardant copolymer of spirocyclic pentaerythritol di(phosphate monochloride) and bisphenol S (SPD-BS) was successfully synthesized and used as a flame retardant in diglycidyl ether of bisphenol A (DGEBA) epoxy resins. The chemical structure of the SPD-BS was characterized using FT-IR and H NMR spectra. The thermal properties were investigated ...
