Q
what bonds polyethylene
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Polyethylene, a versatile and widely used plastic, is made from the polymerization of ethylene (C2H4) molecules. The primary bonds that hold the polyethylene structure together are covalent bonds, formed between the carbon and hydrogen atoms within the monomers. These strong covalent bonds give polyethylene its characteristics like durability and resistance to chemicals. Additionally, between the polyethylene chains, there are weak van der Waals forces which influence the material's melting point and density. High-density polyethylene (HDPE) has stronger intermolecular forces due to closer packing of chains, whereas low-density polyethylene (LDPE) has more branching, leading to weaker intermolecular forces.
