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…
