描述

聚维酮有不同的分子量。分子量越高，粘度越大，因此粘接强度越大。k值表示聚合物与分子量相关的特征黏度，由25℃下测量的水溶液的相对黏度推导而来。分子量与性质之间的直接关系，使得在每个配方中都能以适当的浓度使用适当的等级，以达到最佳的效果。

为了使配方商在选择粘接强度好、易于操作的湿造粒粘合剂时具有灵活性，JRS PHARMA提供了2级湿造粒粘合剂:VIVAPHARM^®PVP K30和VIVAPHARM^®PVP K25。

年级	增殖系数粘度值	典型的动态粘度在20℃的水中10％（g / ml）溶液[MPA·S]
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是低粘度的湿粘结剂，具有良好的粘结强度和易于处理之间的平衡。它在低粘度时具有很高的粘接性，因此在2-5%的粘接性强度和易于处理之间提供了最佳平衡(VIVAPHARM)^®PVP K30)或4-7% (VIVAPHARM^®PVP K25)。

VIVAPHARM^®PVP K30和K25在水和一系列有机溶剂中具有极佳的溶解性，并作为一种具有球形颗粒形态的自由流动的粉末提供。

这确保了快速的分散性和溶剂选择的最终灵活性。由于其非离子性质，不存在与离子原料药相互作用的风险。
