FIREFIGHTING COMBAT WITH FIRE RETARDANTS AT DIFFERENT CONCENTRATIONS

Fighting Fire with Fire: Using Randomized Gossip to Combat Stochastic Scalability Limits

ly, let M be the number of copies of a single multicast that a member receives from the lower dissemination layer. For the Pbcast implementation, since each member gossips a given multicast for O(log(n)) gossip rounds and to randomly chosen targets, we have M = O(log(n)). To maximize the throughput, one would want to minimize the number of copies M of a multicast that a member receives from the...

Properties 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...

Thermal 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...

Probing Synergism, Antagonism, and Additive Effects in Poly(vinyl Ester) (PVE) Composites with Fire Retardants

Playing with fire: the global threat presented by brominated flame retardants justifies urgent substitution.

Few would now deny that the use of organobromine compounds to achieve fire retardancy in a diverse array of products and materials has led to contamination of the ecosphere on a widespread scale. This environmental prevalence and persistence of the brominated flame retardants, coupled with growing evidence of their potential for harm, present all too familiar parallels with the previous generat...
