ASTM D704 Type 2 Elevated Temperature Compound

ASTM D704 type 2 is a grade of melamine moulding compound. The graph bars on the material properties cards below compare ASTM D704 type 2 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.
