LDPE vs. Melamine

LDPE belongs to the thermoplastics classification, while melamine belongs to the thermoset plastics. There are 14 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is LDPE and the bottom bar is melamine.
