透明成核剂NA21(日本)

透明成核剂NA21  透明成核剂NA-21的介绍：NA-21是由日本旭电化（ASAHI DENKA）公司研究及制造的第三代透明成核剂，是目前国际上效能最高，安全性最好的PP透明改性助剂，只需在PP中添加0.1~0.2%，即有明显的增透效能。 NA-21增透PP的特点：◆高透明度、高光洁度◆提高成本效益——PP成本低、密度低，可替代多种较昂贵的塑料◆提高物理性能——高度刚性和较高的热变形温度（耐热度）◆加工热稳定性好——加工过程不产生异味◆缩短PP加工周期——提高PP起始结晶温度17℃，使制件提早脱膜，从而提高生产效率◆也适用于LDPE的透明改性  NA-21增透PP与其他材料的对比： <table border="1" cellpadding="0" cellspacing="0" style="margin: auto auto auto 5.4pt;
