NEMA Industrial Laminate

NEMA laminate is a thermoset plastic. The properties of NEMA laminate include 17 common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare NEMA laminate to other thermoset plastics (top) and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
