孔径为10～100nm、孔密度为109～1012孔/cm3微孔泡沫近几年已越来越受到人们的重视。微孔塑料有许多极好的性能。尺寸小于聚合物结构固有裂纹的微孔不但不影响部件的机械性能,而且能降低固有裂纹产生的影响,阻止在应力作
Pore diameter of 10 ~ 100nm, hole density of 109 ~ 1012 holes / cm3 Microporous foam in recent years has been more and more people’s attention. Microporous plastics have many excellent properties. Micropores smaller in size than the inherent cracks in the polymer structure not only do not affect the mechanical properties of the part but also reduce the effects of inherent cracking and prevent the stress
