Do you know the characteristics of halogen-free plates? Today, the editor of Anhui Xinchen optical new materials Co., Ltd. will introduce it to you.
1、 Insulation of materials
Because P or n is used to replace halogen atoms, the polarity of molecular bond segment of epoxy resin is reduced to a certain extent, so as to improve the insulation resistance and puncture resistance of epoxy resin.
2、 Water absorption of materials
The halogen-free board has less electrons of N and P in the nitrogen phosphorus system oxygen reducing resin than halogen, and its probability of forming hydrogen bonds with hydrogen atoms in water is lower than halogen materials, so its water absorption is lower than that of conventional halogen flame retardant materials. For plates, low water absorption has a certain impact on improving the reliability and stability of materials.
3、 Thermal stability of materials
The content of nitrogen and phosphorus in Halogen-free plates is greater than that of ordinary halogen-based materials, so its monomer molecular weight and TG value are increased. When heated, its molecular motion ability will be lower than that of conventional epoxy resin, so the coefficient of thermal expansion of halogen-free materials is relatively small.
