描述

皮酮有不同的分子量。分子量越高，粘度越大，因此粘合强度。K值表示与分子量相关的聚合物的特性粘度，并且源自在25℃下测量的水溶液的相对粘度。分子量和性质之间的直接相关性使得能够在适当的浓度下在每个配方中使用适当的等级，以达到最佳效果。

为了提供具有良好粘合强度的湿造粒粘合剂的灵活性配方，JRS Pharma提供2种湿粘合剂：vivaPharm.®PVP K30.和vivaPharm.®PVP K25。

年级

k值

10% (g/ml)溶液在20°C [mPa·S]水溶液中的典型动态粘度
vivaPharm.®PVP K25 24.0 - 27.0 3.5 - 5.5
vivaPharm.®PVP K30. 29.0 - 32.0 5.5 - 8.5

vivaPharm.®PVP K30和K25低粘度湿粘合剂，粘合强度与易于处理之间的平衡良好。它在低粘度下具有高度粘性，因此在2-5％的粘合强度和易于处理之间提供最佳平衡（VivaPharm®PVP K30）或4-7％（VivaPharm®PVP K25）。

vivaPharm.®PVP K30和K25在水中具有优异的溶解度和一系列有机溶剂，并且作为具有球形颗粒形态的自由流动粉末供应。

这确保了选择溶剂中的快速分散性和最终的灵活性。由于其非离子性质，它不承受与离子API相互作用的任何风险。
