Performance Evaluation of Polyvinyl Chloride Lubricants
We first reviewed the physical and chemical properties of lubricants,and introduced the principles of testing their compatibility with PVC using the haze method and glass transition temperature method,as well as testing their melting characteristics and heat resistance using DSC and TGA methods respectively.We also introduced the method of evaluating the application efficiency of lubricants briefly by demolding ability and compressibility.Through extensive experiments,we proposed the method of evaluating the gel behavior of lubricants by torque rheometer,providing important reference for lubrication balance in the formulation design of PVC hard products.
