Velvet PC film is a widely evaluated protective material for electronic equipment and has excellent performance. The texture is velvet, another side is matte.The thickness can be 0.125/0.175/0.25/0.375/0.5/0.76mm.All comply with envinronmental standard,with SGS report.First, it has excellent scratch resistance, which can effectively protect the screen base from scratches and wear during daily use. Secondly, although it's velvet textures, the velvet PC film still maintains high transparency and will not affect the screen effect. In addition, it also has display anti-fingerprint properties, which can reduce the impact of grinding fingerprints and stains and keep the screen clean. In addition, the frosted PC film has good wear resistance and flexibility, and can maintain polishing for a long time and adapt to curved surface design. Some velvet PC films also have anti-glare functions, which can reduce screen reflections and improve user comfort.
