Titanium nitride series window film G9005, Relying on the deep integration of aerospace-grade titanium nitride (TiN) material properties and magnetron sputtering technology, titanium nitride window film constructs a multi-layer nanocomposite structure with atomic-level precision. In a vacuum environment, the plasma reaction of titanium ions and nitrogen is precisely controlled by a magnetic field to form a dense and orderly lattice coating on an optical-grade PET substrate. This innovation completely breaks through the physical limits of traditional dyed films and metal films, creating a new era of “reflective intelligent heat insulation.”
