Processing method of high density polyethylene rotational molding

Dec 20, 2016

This processing method of the material to be crushed into powder, making it melt in the heat cycle and flow. Rotational molding uses two types of PE: General and crosslinkable class. General MDPE/HDPE normal density ranges from 0.935 to 0.945g/CC, with narrow MWD to make products with high impact resistance and minimize warping, the melt index range is 3-8. Higher MI grades are usually not applicable, because they do not have a rotational molding products want to impact and resistance to environmental stress cracking.
