Product Introduction
LLDPE (Linear Low-Density Polyethylene) is a specialized type of polyethylene characterized by a linear arrangement of polymer chains with occasional short branches. This molecular configuration enhances its mechanical properties, including superior tensile strength, exceptional flexibility, and high resistance to tearing. Compared to standard low-density polyethylene (LDPE), LLDPE exhibits a more densely packed molecular structure, granting it improved impact durability and greater resilience against environmental stress cracking caused by temperature fluctuations or chemical exposure.
