    可生物降解热熔胶配混料

    关于此产品

    本品是由两种可生物降解聚酯 PBAT 与 PLA 组成的粒料配混料。PLA 是以植物糖为原料的脂肪族聚酯,刚性大、内聚力高;PBAT 是柔性脂肪族-芳香族共聚酯。二者共混后得到的热塑性材料在常温下为固体、不发粘,受热即流动,而这正是热熔胶的全部基础:无溶剂、无固化反应,只有相态变化。

    胶黏剂是可堆肥包装认证中最常见的失分项。整体采用认证材料、却用常规热熔胶组装的包装并不可堆肥——胶黏剂就是杂质,而且因为它在一件大包装中只有几克重,很容易被忽略。常规热熔胶建立在烃类主链之上,不提供任何可供水解或微生物攻击的途径;聚酯主链恰好提供了这条途径。使用性能随共混比例而定:PLA 组分提供内聚强度和更利落的固化,PBAT 组分提供柔韧性和开放时间,两者相互制约——开放时间越长,固化也就越慢。因此,开放时间、固化速度和粘接强度必须结合基材与施胶设备来确定,而不能孤立给出数值。本品以原材料形式供应,供贵司在自有生产线上加工;我们不生产成品。

    应用于可生物降解胶黏剂制造、可堆肥包装组装、生物基聚合物体系以及纸盒与纸箱封合。

    Bio Green Oleo 按聚合物配比、粒料形态,以及对指定基材的开放时间、固化速度与粘接强度的规格要求供应该热熔胶配混料。
