合成树脂瓦表面材料是选用进口的超高耐候性工程树脂制作而成。在自然环境中具有超常的耐久性，它即使长期暴露于紫外线、湿气、热、寒的恶劣条件下，仍能保持其颜色的稳定性。根据美国亚力桑那州和佛罗里达州等日光照射强烈地区户外使用结果证明，可以确保十年颜色变化ΔE≤5。
The surface material of synthetic resin tile is made of imported super high weatherability engineering resin. It has excellent durability in the natural environment, even if it is exposed to ultraviolet, humidity, heat and cold for a long time, it can still maintain its color stability. According to the results of outdoor use in areas with strong sunlight, such as Arizona and Florida, the color change Δ e ≤ 5 can be ensured for ten years.
