Epoxy sheets on the market can be divided into halogen-free and with- halogen . Halogen epoxy sheets with fluorine, chlorine, bromine, iodine, astatine and other halogen elements, play a role in flame resistance. Although halogen elements are flame retardant, if burned, they will release a large number of toxic gases, such as dioxins, benzofurans, etc., with strong taste and thick smoke, which are easy to cause cancer and seriously threaten life and health when entering the human.

  Halogen-free epoxy board, in order to achieve the effect of flame retardant, the main addition is phosphorus element and nitrogen element.  When phosphorous resins are burned, they decompose into metaphosphoric acid.  Metaphosphoric acid can form a protective film on the surface of the epoxy board, and put an end to direct contact with the air. Without enough oxygen, the fire will naturally go out.  And phosphorous resin in the combustion will produce non-flammable gas, further achieve the effect of flame retardant.

   Halogen-free epoxy boards have many other advantages besides being environmentally friendly and flame retardant.  It is often used as an insulating material, so the insulation performance is very good.  It can play the role of support and insulation of various electronic components, in harsh environment, such as humidity, high temperature, can also work normally.  Halogen-free epoxy boards are also thermally stable, thanks to the ability of nitrogen-phosphorus resins to move between molecules when heated.  In addition, it does not absorb water, strong flexibility and other advantages.

  As early as a few years ago, the European Union banned the use of halogen epoxy boards, but due to the high cost of halogen free epoxy boards in China has not been widely used, many manufacturers are still using halogen epoxy boards. With the development of China’s economy and the improvement of people’s awareness of environmental protection, the superior performance of halogen-free epoxy board has been deeply rooted in people’s hearts, and IT is believed that it will be popularized in the near future.
Jiujiang Xinxing Insulation Material Co., Ltd. was founded in 2003, specializing in the production and research and development of various types of epoxy glass cloth laminate, the company has its own research and development team, with the development of export business, according to the needs of different markets, the company developed different levels of temperature resistance halogen-free flame retardant board, widely by European and American countries customers favor.
