El poliuretano (PU) es un elastómero versátil con excelente resistencia a la abrasión y buena resistencia química a aceites, combustibles, grasas y ácidos diluidos.
El poliuretano no está en la fuente Bürkle que proporciona los otros 24 materiales de este sitio. Los datos provienen de PSI Urethanes (ensayados a 21 °C, escala A-B-C), verificados con Engineering Toolbox y Darwin Microfluidics. Las formulaciones de PU varían; siempre verificar con el fabricante.
