Analysis of three kinds of flame retardants 1) Organic halogen flame retardantOrganic halogenated flame retardants refer to organic flame retardants with halogen as the main flame retardant components. Due to their high flame retardant efficiency, low consumption and small impact on the properties of materials, they have been widely used in the flame retardant market since the 1960s. Brominated flame retardants are the re…

Corrosion Resistance of PVC Pipes The major finding of a recent study is that PVC Pipe has the lowest overall failure rate when compared to cast iron, ductile iron, concrete, steel, and asbestos cement pipes. The report concluded that corrosion was a major cause of water main breaks. Escalating deterioration of water and sewer systems due to corrosion, leaks, and breaks in old-technology pipe materials threaten …

Strength & Durability of PVC Pipe PVC Pipes are strong and durable despite their relatively low weight. This makes PVC Pipes suitable for all types of long-term applications including domestic water, sewerage, stormwater, and deep underground piping systems. It stays strong through a range of temperatures resulting in fewer burst pipes and other maintenance issues. PVC-O PIPES ARE TOUGHER THAN THEIR DUCTILE IRON…

Application of synergist in IFR (intumescent flame retardant) In order to further improve the flame retardant efficiency of IFR, some flame retardant synergists are usually added to the extrusion of ordinary intumescent flame retardants to meet the material's requirements for high flame retardant performance and reduce the amount of flame retardant added. From the perspective of scientific research and current research, zeolite, traditi…

Principles and advantages of flame retardant polypropylene (PP) Phosphorus-nitrogen flame retardant is also called intumescent flame retardant. When the polymer containing this kind of flame retardant is heated, a uniform carbon foam layer can be formed on the surface, which can insulate heat, oxygen and smoke. It can prevent the phenomenon of droplets, so it has good flame retardant properties. Intumescent flame retardant systems general…

Mechanisms of brominated flame retardant Due to the low bond energy of the C—Br bond, most bromine-based flame retardants will decompose at 200-300℃. This temperature range is also the decomposition temperature range of polypropylene. Therefore, when polypropylene is thermally decomposed, bromine-based flame retardants will decompose. The fuel also begins to decompose, and can capture the free radicals generated by …

Applications of PVC pipe - Large Diameter PVC-O Pipes-2 When PVC-O Pipe is used for high pressure pipelines they have a number of performance and environmental benefits compared to alternative products. The pipe is highly energy-efficient and environmentally-friendly during all its useful life because of the considerable savings in raw material. DN600 PVC-O Pipe will be less than half the weight of PE and one third of the weight of e…
