Melamine Formaldehyde Moulding Compound

Melamine moulding compound is a thermoset plastic. It can have a moderately low dielectric strength among the thermoset plastics in the database.

The properties of melamine moulding compound include eleven 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 melamine moulding compound 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.
