THERMOMECHANICAL TESTS APPLIED TO THE CHARACTERIZATION OF GREEN POLYURETHANE FOAMS

M. Bagni, D. Granados, M. Reboredo

In recent years, there has been an increasing demand for products of renewable origin with the aim of providing solutions to environmental problems, eliminate or minimize wastes and provide alternatives for the synthesis of new materials, due to the exhaustion of fossil sources. Renewable resources can provide a sustainable alternative to totally or partially replace petroleum-based polymers. Through the design of biobased polymers, which are an innovative technology, it is possible to replace traditional materials with ecofriendly substances. The new polymers are expected to exhibit similar performance to those of petrochemical origin. The most used renewable resources are polysaccharides (mainly cellulose and starch), proteins and vegetable oils, the latest being one of the most important raw materials for the production of polymeric materials.
