The material utilizes high-energy electron beams generated by an electron accelerator to break and reorganize polymer chains, forming a three-dimensional network structure. It features low smoke, halogen-free, non-toxic properties, and excellent flame retardancy. The material complies with GB/T 32129-2015 and meets environmental regulations such as RoHS and REACH. The finished cable meets GB/T 19666-2019, IEC 60332, and UL 1581 FT-2 requirements. It is widely used in densely populated buildings such as high-rise residential complexes, hospitals, and schools.
