Polymer blends are widely utilized for a variety of applications as the particular thermo-physical properties of the individual components comprising the blend result in better overall properties. This is particularly the case of polymer blends used in the automotive industry where impact resistance, toughness, stiffness and paintability all become important issues. The blending of polymers yields a better overall product with the desired end-use properties and characteristics. This application note demonstrates the use of the StepScan DSC technique using the high-performance PerkinElmer Power Compensation DSC that yields enhanced characterization information on materials such as polymer blends.
