HDPE (High Density Polyethylene)High density polyethylene is polyethylene thermoplastic made from petroleum. Known for its large strength to density ratio, HDPE is commonly used in theproduction of plastic bottles, corrosion resistant piping, geomembranes,and plastic lumber. HDPE is commonly recycled, the global HDPE market reached a volume of more than 30million tons.
Polypropylene is used across many industries as a good, general-use polymer. It offers resistance to many standard chemical solutions across the full PH range, making it a products of choice for many applications. The density of PP is between 0.895 and 0.92 g/cm³. Therefore, PP is the commodity plastic with the lowest density. With lower density, moldings parts with lower weight and more parts of a certain mass of plastic can be produced. Unlike polyethylene, crystalline and amorphous regions differ only slightly in their density. However, the density of polyethylene can significantly change with fillers.
