A review of flame retardant polypropylene fibres
Flame retardants for polypropylene (PP) and their potential suitability for use in fibre applications are reviewed. Five principal types of generic flame retardant systems for inclusion in polypropylene fibres have been identified as phosphoruscontaining, halogen-containing, silicon-containing, metal hydrate and oxide and the more recently developed nanocomposite flame retardant formulations. T...
متن کاملSymptomatology during hypoxic exposure to flame-retardant chamber atmospheres.
Hypoxia was studied in 12 men during 63-h exposures to 17 and 13% O2, with the subjects serving as their own controls by repeating the measurements in 21% O2. All test atmospheres were contaminated with 0.9% CO2 to simulate the condition of living aboard submarines. The mean SaO2's were 97-98% in all conditions of 21% O2, 96% in 17% O2 (n.s.), and 92% in 13% O2 (P less than 0.05). The blood con...
متن کاملPerformance of Flame Retardant Wool Fabric Grafted with Vinyl Phosphate
In this paper, a flame retardant dimethyl-2-(methacryloyloxyethyl) phosphate (DMMEP) was applied to wool fabrics by the graft copolymerization technique initiated with potassium persulfate (KPS) in water media. FTIR and SEM testing were used to explore the grafting evidence on the fiber surface, the SEM results show chemical deposition on the wool fiber surface and the scales could not be seen ...
متن کاملAssessing inter-generational transfer of a brominated flame retardant.
Studies have shown that the lipophilic nature of polybrominated biphenyl (PBB) causes it to preferentially accumulate in breast milk posing a potential hazard for suckling infants. The purpose of this study was to examine the inter-generational transfer of PBB from mother to child and whether this association was modified by maternal breast-feeding patterns. One hundred and forty-five mother-ch...
متن کاملFlame Retardant Luffa Fiber Reinforced Composites with Epoxy Resin Matrices
In current years composites have concerned considerable importance as a potential operational material. Low cost, light weights, high specific modulus, renewability, and biodegradability are the most basic & common attractive features of composites that make them useful for industrial applications. Luffacylindrical locally called as “sponge-gourd” is one such natural resource whose potential as...
