EPDM Composites filled with Corn Starch and thermoplastic Starch

摘要

In recent years, chemical industry is focused on research and utilization of natural resources, for example lignin, cellulose and starch. The main issue of rubber product is caused by constant increase of rubber waste, their landfiling and lack of reduction ability. This work is focused on the application of corn starch and thermoplastic starch as a filler in EPDM rubber. The influence of natural filler on the curing process and physical-mechanical properties of EPDM blends was observed. The main goal was to find suitable amount of used corn and thermoplastic starch in combinations with other additives of rubber compounds in order to support biodegrability and to reduce the costs of the final products. The corn starch was applied in natural form, and also after modification as a thermoplastic starch.
