ASTM D704 Type 6 Wood-Melamine Compound
ASTM D704 type 6 is a grade of melamine moulding compound. The graph bars on the material properties cards below compare ASTM D704 type 6 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.
