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

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 addi-tive 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.
