PA6 flame retardant is a plastic that is free from halogens and phosphorus, with a limited oxygen index of 40%, enabling flame resistance and self-extinguishing capabilities, and it has received a UL94-V0 fire rating. Furthermore, its low-density characteristic (1.17g/cm3) provides lightweight properties compared to steel (7.85g/cm3), offering structural advantages. It complies with the European railway vehicle standard DIN EN45545-2:2013 and has applications in railway vehicle construction, the aerospace industry, shipbuilding, mining, and the electrical industry, among others.
