The effect of selected natural fillers on the mechanical properties of low-density polyethylene

The popularity of using natural waste products in different branches of industry, including polymer processing, results from the emphasis of international nature conservation organizations on ecological and environmental problems, such as recycling, storage and the disposal of waste products. This paper investigates the effect of two natural fillers: wheat bran and pumpkin seeds obtained from food industry waste products, on selected mechanical properties of LDPE molded pieces. The polymer blends are examined with respect to their basic mechanical properties and microstructure.
