Photo-Oxidative and Soil Burial Degradation of Irrigation Tubes Based on Biodegradable Polymer Blends.

Irrigation tubes based on biodegradable polymers were prepared via an extrusion-drawing process by Irritec and compared to conventional pipes made of high-density polyethylene (HDPE). A commercial polylactide/poly (butyleneadipate--butyleneterephthalate) (PLA/PBAT) blend (Bio-Flex) and Mater-Bi were used. The polymers were characterized from rheological and mechanical points of view.
