- Comments
- The polymer has up to 7 500 000 monomers units and different branching degrees. It is classified according to its density and branching: very-low-density polyethylene (VLDPE), low-density polyethylene (LDPE), Linear low-density polyethylene (LLDPE), medium-density polyethylene (MDPE), Cross-linked polyethylene (PEX or XLPE), High-density cross-linked polyethylene (HDXLPE), high-density polyethylene (HDPE), Ultra-low-molecular-weight polyethylene (ULMWPE or PE-WAX), High-molecular-weight polyethylene (HMWPE), and ultra-high-molecular-weight polyethylene (UHMWPE)
