Polypropylene is an addition polymer made from the monomer propylene, and it is widely used. It is defined by a density range of 0.946 g/cm3 for crystalline.
PP prime grade, off-grade, reprocessed pellets (regranulates) and agglomerates.
natural injection molding
white injection molding
white color with talc
black copolymer and homopolymer
regranulates: black or mix color
HDPE is defined by a density of greater or equal to 0.941 g/cm3. It has a low degree of branching and thus stronger intermolecular forces and tensile strength.
HDPE prime grade, off-grade, reprocessed pellets (regranulates).
