Linear low-density Polyethylene The structure of linear low-density polyethylene (LLDPE) has a linear backbone with short and uniform branches (unlike longerbranches of LDPE). These short branches are able slide against each other upon elongation without becoming entangled like LPDE. It is structurally similar to LDPE. Applications: LLDPE FILM PP (HOMO POLYMER) Typical Application: PP PIPE …
Low Density Polyethylene Low-density Polyethylene (LDPE) is a semi-rigid polymer with low crystallinity (~50-60%). The LDPE is composed of 4,000-40,000 carbon atoms, with many short branches. Compared to HDPE, it has a higher degree of short and long side-chainbranching. LDPE Grades Applications:
High Density Polyethylene (HDPE) is a cost-effective thermoplastic with a linear structure. It has no or low degree of branching. It isflexible, translucent/waxy, and weather resistant. The chemical structure of HDPE is: -CH2-CH2-CH2-CH2-CH2-CH2-CH2–HDPE Molecular Structure HDPE is more rigid due to high crystallinity (> 90%). This also means it is less transparent than LDPE & …
