A HAAKE PolyLab OS torque rheometer, equipped with a Mixer was used to test four different soft PVC samples. The type and amount of plasticizer was varied. The corresponding torque curves helped to differentiate the formulas. The PolySoft Mixer data evaluation is explained in detail in this application note, and valuable hints are given for substituting PVC blend ingredients, e.g.plasticizers, stabilizers. 多功能轉(zhuǎn)矩流變儀HAAKE PolyLab OS
