Phosphorus flame retardants: properties, production, environmental occurrence, toxicity and analysis.
Since the ban on some brominated flame retardants (BFRs), phosphorus flame retardants (PFRs), which were responsible for 20% of the flame retardant (FR) consumption in 2006 in Europe, are often proposed as alternatives for BFRs. PFRs can be divided in three main groups, inorganic, organic and halogen containing PFRs. Most of the PFRs have a mechanism of action in the solid phase of burning mate...
متن کاملElectronic device encapsulation using red phosphorus flame retardants
This paper presents an analysis of the use of red phosphorus as a flame retardant material in encapsulated microcircuits and discusses the reliability risks. Chemical reactions, which can arise when red phosphorus is exposed to ambient humidity to form highly mobile ions and oxygen-containing phosphorus acids, are presented. These ions and acids can induce electro-chemical migration, causing sh...
متن کاملProperties of Flat-Pressed Wood Plastic Composites Containing Fire Retardants
This study investigated physical, mechanical, and fire properties of the flat-pressed wood plastic composites (WPCs) incorporated with various fire retardants (FRs) [5 or 15% by weight (wt)] at 50 wt % of the wood flour (WF). The WPC panels were made from dryblended WF, polypropylene (PP) with maleic anhydridegrafted PP (2 wt %), and FR powder formulations using a conventional flat-pressing pro...
متن کاملExploring the Modes of Action of Phosphorus-Based Flame Retardants in Polymeric Systems
Phosphorus-based flame retardants were incorporated into different, easily preparable matrices, such as polymeric thermoset resins and paraffin as a proposed model for polyolefins and investigated for their flame retardancy performance. The favored mode of action of each flame retardant was identified in each respective system and at each respective concentration. Thermogravimetric analysis was...
متن کاملThermal Stability and Fire Properties of Salen and Metallosalens as Fire Retardants in Thermoplastic Polyurethane (TPU)
This study deals with the synthesis and evaluation of salen based derivatives as fire retardants in thermoplastic polyurethane. Salens, hydroxysalens and their first row transition metal complexes (salen-M) were synthesized (Copper, Manganese, Nickel and Zinc). They were then incorporated in thermoplastic polyurethane (TPU) with a loading as low as 10:1 weight ratio. The thermal stability as we...
