Understanding Rheology of Thermoplastic Polymers GENERAL CONSIDERATIONS Rheological testing of thermoplastic materials can be performed on both solid samples and on melts. This is important because the choice of material form and physical state is more than a matter of convenience: Product performance issues usually are related to solid samples properties; process ability issues…
Application of Rheology of Polymers INTRODUCTION TO THE APPLICATION OF POLYMER RHEOLOGY Polymers are viscoelastic fluids, which behave viscous or elastic, depending on how fast they flow or are deformed in the process. The silicone putty test is a good demonstration of this pheno-menon (Figure 1). If a ball of silicone is subjected to a…
Analytical Rheology Analytic rheology is the subject of determining the microstructure of a material from measurements of its viscoelastic response. Analytic rheology is an extension of analytic chemistry in much the same sense as other analytic methods predicated on flow properties. Intrinsic viscosity is an example of an analytical technique that falls into this category.…
