El POM-C y el POM-H son ambos acetal, ambos se suministran en barra y placa, y ambos se presupuestan a menudo simplemente como acetal. No son intercambiables en todas las aplicaciones.<\/p>\n\n
El homopol\u00edmero es algo m\u00e1s duro, m\u00e1s r\u00edgido y alrededor de un diez por ciento m\u00e1s resistente, con mejor resistencia a la fluencia bajo carga sostenida. Tambi\u00e9n tiene un punto de fusi\u00f3n cristalino m\u00e1s definido, lo que lo hace m\u00e1s propenso a la porosidad en la l\u00ednea central de las barras extruidas de gran di\u00e1metro. Si mecaniza al torno una barra de 150 mm hasta un buje de 140 mm con el centro taladrado, la porosidad se convierte en su tasa de rechazo.<\/p>\n\n
El copol\u00edmero tiene una ventana de procesado m\u00e1s amplia, mucha menos porosidad en secciones gruesas y mejor resistencia al agua caliente y a los \u00e1lcalis d\u00e9biles. Para cualquier pieza de m\u00e1s de 80 mm de di\u00e1metro, o cualquier pieza que se mecanice cerca de la l\u00ednea central, usamos POM-C por defecto y rara vez tenemos motivo para cambiarlo. El POM-H se gana su lugar en piezas peque\u00f1as, muy cargadas y de tolerancias ajustadas, donde la rigidez adicional compensa.<\/p>\n\n","protected":false},"excerpt":{"rendered":"
