Change in Compressive Properties of Polypropylene/Degra-Novon Polymer Blends Due to Accelerated Weathering Tests

Abstract

After accelerated weathering, dynamic and static compressive properties of polypropylene and Degra-Novon blends were measured using a split Hopkinson pressure bar and universal testing machine. Degra-Novon is an additive mixed with traditional plastics that promotes the spontaneous decomposition of the plastics by sunlight, heat, and microorganisms in soil and water. The use of Degra-Novon achieves a low-cost, biodegradable polymer. The change in yield stress and Young's modulus were examined in detail. The relationship between the compressive properties, differential scanning calorimeter results, and Fourier transform infrared spectroscopy data was discussed.
