Laminados de grado NEMA

 

Los materiales de grado Lamitex® que cumplen con las especificaciones NEMA se utilizan en más de 60 mercados y cientos de aplicaciones anualmente.

Podemos suministrar pequeñas y grandes cantidades de láminas, barras, tubos (redondos / cuadrados / rectangulares), ángulos y piezas fabricadas a medida. Nuestra amplia gama de composites nos facilita designar el mejor ajuste para sus requisitos de aislamiento o rodamientos de compuesto.

A continuación, encontrará una tabla de referencias cruzadas que contiene algunos de los materiales laminados de Lamitex® que cumplen con las especificaciones de NEMA.
