    • Provided are methods for producing a high strength, but easily deformed, polystyrene foam board that can endure repeatedly deformations from its original configuration into more complex curved shapes without damaging the board integrity or substantially reducing its structural strength. Also provided are rigid polystyrene foam boards produced by this method that exhibit improved bending and impact resistance while substantially retaining or improving other properties, for example, the thermal dimensional stability and fire resistance, exhibited by corresponding conventional XPS foam boards. The foamable compositions may incorporate one or more of a variety of polymer processing aids for the purpose of altering the performance of the final foam products, thereby allowing the properties of the final foam product to be customized to some degree.
    • 提供了用于生产高强度但容易变形的聚苯乙烯泡沫板的方法,其可以承受从其初始构造重复变形到更复杂的弯曲形状,而不损害板完整性或显着降低其结构强度。 还提供了通过该方法制造的刚性聚苯乙烯泡沫板,其显着改善了弯曲和抗冲击性,同时基本上保持或改善了相应的常规XPS泡沫板所显示的其它性能,例如热尺寸稳定性和耐火性。 可发泡组合物可以掺入多种聚合物加工助剂中的一种或多种,​​以改变最终泡沫产品的性能,从而允许最终泡沫产品的性质在一定程度上定制。
