淀粉基生物降解薄膜性能独特

  中科院长春应化所在中国科学院知识创新工程重大项目和吉林省省长基金的资助下,在淀粉基完全生物降解塑料的研发工作上取得了较大进展,获得了一批拥有自主知识产权的技术成果。    
  据了解,中科院长春应化所通过放大试验、小批量生产示范为技术转化奠定了一定的基础,目前研发的主要产品有淀粉基发泡材料和淀粉基生物降解薄膜。    
  淀粉基发泡材料是以85%以上的淀粉辅以其他可生物降解物质,通过特定工艺制备而成。淀粉基生物降解薄膜则采用独特的三元增塑体系制成,淀粉含量60%以上,机械性能好,断裂强度为12~30MPa,断裂伸长率可达50%~250%,与同等厚度的PE薄膜相当,而且印刷性能优良,印刷前不需处理,适用于购物袋、垃圾袋、杂物袋等。
