Product Information

Novas tecnologias vem sendo desenvolvidas para a recuperacao e inertizacao das areias, porem as resinas disponiveis atualmente tem como limitacao ecologica sua origem quimica. Apos sua utilizacao estes moldes sao descartados, e assim, os ligantes toxicos tornam-se um problema ambiental. Nos ultimos anos, porem, o aumento das exigencias das regulamentacoes ambientais tem impactado diretamente na industria de fundicao, principalmente em relacao ao descarte dos materiais utilizados, que se torna cada vez mais oneroso as empresas. Desta maneira, a substituicao destes ligantes por compostos organicos derivados de fontes renovaveis como a resina poliuretana derivada do oleo de mamona minimiza os impactos ambientais. A possibilidade dessa substituicao pode conduzir o processo de fundicao rumo a sustentabilidade, necessaria devido ao aumento do rigor da legislacao ambiental aplicada as operacoes industriais, alem dos altos custos do descarte.
