The raw materials of GFK antibacterial board are all made of pure natural green materials, with a molding temperature of 150 degrees and a solid rest degree of more than 99.9%, so there will be no volatilization of harmful substances. The national authorized testing center refers to USEPA3052:1996 digestion method to process samples and uses LCP measurement for quantitative measurement. (LUSEPA6010C:2007) detection, lead, cadmium, mercury, refer to USEPA3540:1996 to process samples. GC-MS measurement (LUSEPA8270D:2007) detects ten items of polybrominated biphenyls (PBBS). All ten items of polybrominated biphenyls (PBOES) are far higher than the national safety standards. For details, see the ROHS test report.
