Biodegradable polyurethane foams

Biodegradable polyurethane foams

Paper in proceedings (conference paper)

Flexible biodegradable polyurethane foams (BIO-PUR) were prepared by one-shot process using commercially available coreactants and modified by substituting biodegradable additive based on the acetylated starch (AS), acetylcellulose (AC), 2 hydroxyethylcellulose (HEC) and carboxymethylcellulose sodium salt (CMC) for 5 or 10 wt% of commercial polyether polyol. The BIO-PUR foams were characterized by FTIR, TGA and polarization microscopy. Resulting BIO-PUR foams were undergone microbial degradation using the mixed culture of Thermophillus sp. and yeast strain Aureobasidium pullulans. Ecotoxicity of BIO-PUR foams freshwater extracts was evaluated using alternative crustacean toxicity test Thamnotoxkit FTM.
