The coloration of plastics is an important quality feature of medical devices, and it is most frequently done by using masterbatches. This study investigates the influence of masterbatches with different carrier resins on the impact resistance and the morphology of an acrylonitrile-butadiene-styrene (ABS)/styrene-acrylonitrile (SAN) blend. The experimental results were compared with thermodynamical models based on Hansen and Flory–Huggins theory. The models, as well as notched impact testing, indicated strong immiscibility and incompatibility when using a masterbatch carrier based on polystyrene (PS). Immiscibility was confirmed by morphology studies that revealed the formation of PS-droplets with increasing masterbatch content. Masterbatches based on ABS and SAN showed no significant impact and theoretical calculations were in good accordance with mechanics and morphology. The proposed theoretical calculation of solubility between blend partners potentially allows a prediction for selecting a suitable masterbatch carrier.

通过合理选择用于医疗器械应用的色母粒确保患者安全——调查由基于苯乙烯类聚合物的不同色母粒着色的 ABS/SAN 混合物的特性的案例研究

塑料的着色是医疗器械的一个重要质量特征，最常见的是使用色母粒。本研究调查了具有不同载体树脂的母粒对丙烯腈-丁二烯-苯乙烯 (ABS)/苯乙烯-丙烯腈 (SAN) 共混物的抗冲击性和形态的影响。实验结果与基于 Hansen 和 Flory-Huggins 理论的热力学模型进行了比较。这些模型以及缺口冲击测试表明，当使用基于聚苯乙烯 (PS) 的母粒载体时，它们具有很强的不混溶性和不相容性。形态学研究证实了不混溶性，揭示了随着母料含量增加而形成 PS 液滴。基于 ABS 和 SAN 的色母粒没有显示出显着的影响，并且理论计算与力学和形态非常吻合。所提出的共混伙伴之间溶解度的理论计算可能允许预测选择合适的母料载体。
