What is the flame retardant principle of 3240 epoxy resin board?

Due to the rapid development of polymer chemistry and electrical industry in recent years, the scope of insulation materials is particularly obvious. For example, the heat resistance and flame retardant performance requirements of 3240 epoxy resin boards are also getting higher and higher, and most applications require higher insulation materials. The electrical strength, mechanical function and electrical insulation function. From the current point of view, most insulating materials are made of halogen-containing flame retardants, which will not only cause serious pollution to the environment but also cause damage to the human body. So what is the flame retardant principle of 3240 epoxy? Today’s electronic editor will introduce it to us.
