In fact, friends who know about flame retardants should know that, in general, the common method of testing flame retardant flame retardancy by quick and convenient keys is mainly by lighter test. So is it feasible to test sample performance with lighter?



It is easy to judge the halogen system by flame retardant testing directly with lighter, because the mechanism of the system determines that the density of the product has little effect on the flame retardant effect. The same is true for hydroxide systems.




But for nitrogen and phosphorus series charring flame retardant, due to the dependence of charring mechanism, the compactness of products has a greater impact on flame retardant. For example, the compactness of newly extruded strips is limited, there may be some pore inside, which has side effects on charring. The compactness of products after injection is greatly enhanced, and the effect of charring is more rapid.



Therefore, when testing flame retardants with lighters, we must distinguish the object, so that the test results will be more ** and easier to identify the flame retardant grade of flame retardants.



Above is the whole content about the feasibility of testing the flame retardant performance with lighter introduced by Xiaobian. I hope that this knowledge can continue to pay attention to our website, so as to get more news information.
