A thermoplastic synthetic resin such as polyethylene or ethylene-vinyl acetate copolymer resin containing 0.1 to 10 wt. % of a specific additive selected from specific classes of compounds, namely saturated higher fatty acid amidas, saturated higher aliphatic amines and complete esters of saturated higher fatty acids is found to be very suitable for production of expanded articles and can be easily formed into expanded articles with little shrinkage after expansion, free from creases on the surface or cracks on the cell walls, and having excellent characteristics such as good closed cellular characteristic, high compressive strength, low density. etc.
一种热塑性合成树脂,如聚乙烯或乙烯-醋酸乙烯共聚物树脂,含有 0.1 至 10 wt.%的特定添加剂,这些添加剂选自特定类别的化合物,即饱和高级脂肪酸酰胺、饱和高级脂肪族胺和饱和高级脂肪酸完全酯,这种添加剂非常适合用于生产发泡制品,而且可以很容易地制成发泡制品,发泡后收缩率小,表面无皱褶,细胞壁无裂纹,具有良好的封闭细胞特性、高抗压强度、低密度等优异特性。
