树脂瓦的面层材料最为关键，合树脂瓦的好坏，还与表面材料的使用量，和共挤技术有关系。面层材料的选用直接影响 树脂瓦的使用寿命，恒兴树脂瓦选用优秀的超耐候材料ASA，通过表面共挤最后成型。标准的合成树脂瓦可以长期抵御酸，碱，盐等各种化学物质腐蚀，实验浸泡盐，碱及60%以下各种酸中24小时无化学作用。产品的耐候性直接导致了合成树脂瓦的使用寿命。
The surface material of resin tile is the most critical, and the quality of resin tile is also related to the amount of surface material used and co-extrusion technology. The choice of surface material directly wushui.37ix.com.cndiaosurw.37ix.com.cnzhagungp.37ix.com.cnzhibanx.37ix.com.cnwalengzhi.37ix.com.cn xianweisu.37ix.com.cnaffects the service life of resin tile. Hengxing resin tile uses excellent super weatherproof material ASA, which is finally formed by surface co-extrusion. Standard synthetic resin tile can resist the corrosion of acid, alkali, salt and other chemical substances for a long time. It has no chemical action for 24 hours in the experiment soaking salt, alkali and all kinds of acids below 60%. The weatherability of the product directly results in the service life of the synthetic resin tile.
劣制的合成树脂瓦面层采用其颜料会产生化学反应，甚至产生严重褪色。
Poor synthetic resin tile surface with its pigments will produce chemical reactions, or even serious fading.
