Polypropylene is stronger that polyethylene. High resistance to environment. Have higher melting point. The chemical reason is that polypropylene have triple bond carbon. However, polyethylene have only double carbon bonded to each other. 8 people found this useful.
Polyethylene (abbreviated PE) or polyethene (IUPAC name polyethene or poly(methylene)) is the most common plastic. The annual global production is approximately 80 million tonnes.or common commercial grades of medium-and high-density polyethylene the melting point is typically in the range 120 to 180 Â°C (248 to 356 Â°F). The melting point for average, commercial, low-density polyethylene is typically 105 to 115 Â°C (221 to 239 Â°F).
