挤塑板又称XPS板，是连续挤出型聚苯乙烯泡沫塑料的简称，它是聚苯乙烯原料加上其他辅料与聚合物，通过加热混合同时注入催化剂，然后挤塑压出成型而制v检查井钢模具 隔离墩模具 隔离墩钢模具 流水槽模具 U型槽模具 螺杆启闭机 卷扬式启闭机 铜雕佛像 造的硬质泡沫塑料板，XPS板具有完美的闭孔蜂窝结构，这种结构让XPS板有极低的吸水性（几乎不吸水）、低热导系数、高抗压性、抗老化性（正常使用几乎无老化分解现象）。
Extruded plate, also known as XPS board, is the abbreviation of continuous extruded polystyrene foam. It is a rigid foam board made of polystyrene raw material plus other excipients and polymers, which is mixed by heat and injected into the catalyst, and then extruded and extruded. The XPS board has a perfect closed cell honeycomb structure. This structure makes the XPS board have very low water absorption (hardly absorbency) and low. Thermal conductivity, high compressive resistance and aging resistance (almost no aging decomposition phenomenon in normal use).
