Introduction
LDPE (Low Density Poly Ethylene) is an important polymer used in the manufacture of plastic products. This application note details Dynamic Mechanical Analysis (DMA) experiments over a temperature and frequency range. The combination of frequency and temperature are important factors for the practical application of LDPE. Relaxations are frequency dependent, so they will occur at different temperatures depending on the distortion frequency the material is subjected to. A temperature scan of the material will be discussed, as will a frequency sweep at a series of discrete temperatures.
