Product Introduction
LLDPE (Linear Low-Density Polyethylene) is an engineered polyethylene derivative defined by a linear polymer backbone with sporadic short-chain branching. This structural design strengthens its mechanical performance, delivering excellent tensile strength, remarkable flexibility, and outstanding resistance to tearing. In contrast to conventional LDPE, LLDPE features a tightly packed molecular configuration, which enhances its impact durability and elevates its ability to withstand environmental stress cracking induced by thermal cycling or chemical interactions.
