[0033] Working principle: In this tape, the first flame retardant coating 4 can select phosphorus-nitrogen composite halogen-free flame retardant. The halogen-free flame retardant coating does not contain harmful halogen elements and therefore has higher environmental protection, heat resistance and stability.
