Two types of commercially applied Ethylene/Vinyl Acetate Copolymers (EVA) for encapsulation
of photovoltaic modules were investigated by the thermal analysis methods of
Differential Scanning Calorimetry (DSC) and Dynamic Mechanical Analysis (DMA) in the
temperature range from 150 C to 200 C. Glass transition, crystal melting and crosslinking
were analyzed. The aims of the investigations were to gain more information for
incoming goods control and to get information about the whole temperature dependent
material properties in the investigated temperature range, starting at very low temperatures
up to the crosslinking temperature region.
