在包装应用中,人们常常误解闭孔泡沫塑料材料比重和缓冲性能间的关系。然而,正确理解材料比重与缓冲性能的关系可以帮助包装工程师,获得最佳缓冲设计方案。 许多设计者认为:低密度闭孔泡沫塑料缓冲性能较好。而且,由于这种材料往往价格较低,因此高密度材料有更高的使用价值。事实上,这种观点常常是错误的。材料密度与其缓冲性能的变化并无直接对应关系,而是密度的变化对材料的承载能力有较 In packaging applications, people often misunderstand the relationship between the specific gravity and cushioning properties of closed cell foam materials. However, a correct understanding of the relationship between material weight and cushioning performance can help packaging engineers get the best cushioning design. Many designers think: Low density closed cell foam cushioning performance is better. Furthermore, high-density materials have higher value due to the lower cost of such materials. In fact, this view is often wrong. There is no direct correspondence between material density and its change in cushioning properties, but the change in density has a greater bearing capacity on the material
