As the world's leading inspection, identification, testing and certification organization, SGS's certification is highly authoritative. After strict testing by SGS, the Polyurethane Clear Protective Film technology has excellent performance in antibacterial properties, wear resistance, temperature resistance, transparency retention and other aspects, which fully proves the reliability and advancement of the technology.
HEWEI polyurethane transparent protective film uses advanced polyurethane materials, which have a unique molecular structure and give the protective film many excellent properties. The high strength and flexibility of polyurethane materials enable it to effectively resist various external impacts. At the same time, it also has excellent wear resistance, which can maintain the integrity of the protective film for a long time and provide lasting protection for the protected objects.
The antibacterial polyurethane cushion material independently developed by Hewei Technology officially passed the national invention patent certification on August 28, 2018, and the patent number is CN104892893B. This invention patent certificate was issued by the State Intellectual Property Office of the People's Republic of China. It is not only a high recognition of the innovative wisdom of Hewei scientific research team, but also a strong proof of Hewei deep technical background in the field of material research and development. This patent achievement makes Hewei stand out in the cushion material market and establishes its leading position in technology.
The test results show that the cushion material has a significant inhibitory effect on common pathogens such as Klebsiella pneumoniae, Escherichia coli, and Staphylococcus aureus. It can be clearly seen from the comparative test chart that the growth of bacteria in the sample area containing antibacterial agents is effectively controlled, while the areas without antibacterial agents are multiplied by bacteria. This fully shows that the use of Hewei antibacterial polyurethane cushion materials can effectively reduce bacterial growth and provide users with a healthier and cleaner sitting experience.
