In non-metallic materials, fiber reinforced polyester material has excellent anti-aging properties. The anti-aging performance test showed that the maximum aging thickness of the surface was less than 50μm in 20 with different climatic zones. The minimum thickness of most cases is 5mm, which is less than 1% of the box thickness, so it has no obvious effect on the mechanical properties of the box. The company has adopted a special UV-resistant surface treatment process, which reinforces its anti-aging properties.
