Answer to Question 1

The polycarbonate is tougher, stronger, and more scratch resistant.

Answer to Question 2

The major problem with UHMWPE is the difficulty in melting and processing the material. By adding a low molecular weight polyethylene, the material will melt and lubricate the higher molecular weight mass, thus allowing the material to be processed even though it is not fully melted.
