Due to the use of life, the safety performance of many materials has been taken seriously, such as the flame retardant properties of the products. Simply speaking, the purpose of the flame retardant material is to suppress combustion or to achieve the purpose of delaying combustion, so that it is safer to use in life. From the point of view of the added materials of the flame retardant, it is divided into: organic and inorganic, halogen and non-halogen. For the specific added flame retardant, depending on the performance and the use requirements, there will be different choices.

For the relevant manufacturers or users of the long fiber reinforced composite engineering plastics industry, there will be a question: Can LFT long fiber modified plastics be added with flame retardant? The answer is yes, can be added.

In addition, LFT long fiber reinforced PEEK material is inherently flame retardant, so it does not need to be added.

For LFT long fiber thermoplastic materials or traditional materials, the principle of adding flame retardants is the same: by adding a flame retardant in a certain proportion of plastics, the oxygen index is increased, thereby improving the flame retardant effect. Of course, the oxygen index only indicates the flammability of the material and the flame retardancy of the flame retardant. A series of parameters, such as thermal autoignition critical parameters, hot spot combustion energy, and thermal auto-ignition temperature, should be used. In general, when a plastic containing a flame retardant is burned, the effect of the flame retardant may be different under different reaction conditions, different materials, and flame retardants.
