Prepare biodegradable polyurethane foams, including poly (hydroxybutyrate) polymers, renewable source polyols, isocyanates and additives based mixtures intended to prepare biodegradable polyurethane foams Composition and biodegradable polyurethane foam. In the process, poly (hydroxybutyrate) + polyol, isocyanate and additives are premixed in a specific mixer and once homogenization is achieved, the mixture is injected into the mold for augmentation. After curing, the resulting product exhibits foam properties with density, toughness and cell size that vary with the proportion of reagents and allow the production of several products. |
