Polyethylene, linear [MW ~ 52,000]

NIST Standard for determining melt flow rate in polymers. Melt flow rate is widely used in polymer technology as a product specification since this value, which includes a statement of the load and temperature under which it is obtained, gives an indication of the processing properties of the polymer.1, 2
