High density polypropylene
WebThe crystallinity exhibited by polypropylene is intermediate to those of low-density polyethene and high-density polyethene. The three primary types of polypropylene include the homopolymer, the block copolymer, and the random copolymer. The copolymerization is usually carried out with a combination of propylene and ethylene.
