Data from E.N. Cabrera-Alvarez and Colleagues Advance Knowledge in Flame Retardants

June 23, 2014

By a News Reporter-Staff News Editor at Nanotechnology Business Journal -- Research findings on Flame Retardants are discussed in a new report. According to news reporting originating in Coahuila, Mexico, by VerticalNews journalists, research stated, "The modification of magnesium hydroxide (MH) with triethoxy vinyl silane (TVS) was carried out via three different methods and the results are discussed with respect to their effect on the flame retardant and the tensile properties of high density polyethylene (HDPE) nanocomposites. Via a xylene suspension of MH and TVS, via a water suspension of MH and TVS, and via powder mixing of MH and TVS."

The news reporters obtained a quote from the research, "It was found that in all three cases, SiOMg bonds formed on the MH particles surface. Also, this silane modification induced a certain level of particle agglomeration, but without modifying their morphology or particle size. It was also found that the flame retardant properties of the HDPE nanocomposites did not improve because of the use of silane modified MH. During the flame retardant tests, all nanocomposites passed the UL-94-HB, but it was observed that the flame permanence time was longer when using modified MH. The tensile properties were negatively affected by the addition of unmodified MH; the nanocomposites became hard and brittle, with reduced flexibility."

According to the news reporters, the research concluded: "This negative effect was diminished when using silane modified MH. POLYM. COMPOS., 35:1060-1069, 2014."
