Brass rigid fire hose and hydrant adapters provide good strength, ductility, and corrosion resistanceThey are more heat resistant than aluminum rigid fire hose and hydrant adaptersThese fittings will not rotate as a hose is moved, making them less likely to loosen or break than swivel adapters.
In this paper, boric acid was loaded on the surface of expandable graphite (EG), polyvinyl alcohol (PVA) and silane coupling agent (KH) served as a bridgeThe purpose of this study was to improve the flame retardant properties of semi rigid polyurethane, meanwhile, the mechanical properties of the foam got amelioratedPVA was dissolved in hot water.
That which is claimed is A rigid polyurethane syntactic foam consisting of a cured product obtained from a mixture consisting essentially of the composition obtained by mixing an organic polyol, a polyisocyanate, microballoons, a catalyst for the reaction between the organic polyol and polyisocyanate, and a substantially colorless, compatible flame retardant having a viscosity less than
This paper presents the results of a study aimed at assessing the flame retardancy effect of a halogen free, phosphorus containing hyperbranched aromatic flame retardant with a rigid structure in an epoxy resin, specifically in diglycidyl ether of bisphenol A (DGEBA) cured with isophorone diamine (IPDA).
[ ] The flame retardant T modes of action and chemical decomposition mechanisms of a series of phosphorus based hyperbranched polymers has been examined in detail, highlighting the multifunctional qualities of these flame retardant additives.[, ] A rigid aromatic phosphorus containing hyperbranched flame retardant
Gutter oil biodiesel based flame retardant rigid polyurethane foams were potential candidates in fire insulation materials for future application in architecturesAbstract In this study, gutter oil biodiesel based polyols (GOBP) and a reactive type flame retardant named diethyl bis( hydroxyethyl) aminomethylphosphonate (BHAPE) were both
New types of flame retardant coatings for rigid polyurethane foam (RPUF) are developed using mixtures of amorphous sodium polyborate (SPB) and various polysaccharidesBased on our previous research reporting that the RPUF coated with a mixture of SPB and starch shows high flame retardancy, polysaccharides such as carboxymethyl cellulose, hydroxyethyl cellulose, glucomannan, hydroxypropyl
Unfortunately, RF flame retardant was withdn from the marketThe removal of this product has created a need for a replacement flame retardant in the rigid polyurethane market, especially for pour in place panel applicationsIn general, halogenated flame retardants tend to be solids or high viscosity liquids.
Atkore has developed self extinguishing flexible stainless steel conduit and fittings for use in harsh environment applicationsThe flame retardant conduit and fittings are halogen free and feature low smoke toxicity propertiesWith a rating up to IP, the Low Smoke Zero Halogen conduit and EXD Flameproof Barrier Gland are liquid tight and prevent contamination from oils, dirt, dust,
