Flame retardant: an essential patron saint of safety On July 6, 2013, Asiana flight 214 crashed when it landed in San Francisco, its fuselage caught fire and emitted thick smoke. In this accident, although the plane caught fire, the vast majority of passengers survived smoothly. It is a kind of chemical product widely existing in our life, but often ignored, that is flame retardant. As a conventional means of fire prevention, flam…

Effects of Flame Retardant and Glass Fiber on the Properties of PA66 Due to the needs of electronic product applications, PA66 must have certain flame retardancy and relative tracking index (CTI) properties. Also, depending on product strength requirements, it may be necessary to add glass fibers to the PA66 material. Commonly used flame retardants are nitrogen flame retardants, bromine flame retardants and red phosphorus. (1) Under normal circ…

What are the standards for the selection of flame retardants for nylon? Nylon has excellent properties and is widely used. Unmodified nylon has low flame retardancy, vertical combustion can only reach UL94V-2 level, oxygen index is about 24%, it will drip during combustion, it is a flammable material, and it is very easy to use in the process. Yes. catch fire. Therefore, reformed nylon flame retardants have become a common concern and research topic…

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…

Not all flame retardants are the same Manufacturers include specific flame retardants in their products based on the product’s attributes, properties, use, and potential ignition threats. Product manufacturers use flame retardants to protect materials from igniting.The term “flame retardant” refers to a function, not a distinct family of chemicals. Many different chemistries, with different properties and molecul…

What are flame retardants ? Flame retardants are derived from naturally-sourced elements and are incorporated into materials such as plastics, textiles, foams, and paints. Flame retardants can be liquids or solids. They can be chemically transformed to create a new fire resistant material (reactive) or physically incorporated into a material (additive).Reactive flame retardants are incorporated into the p…
