Mechanical and Thermal Properties of HDPE/LDPE Blends for Industrial Applications

Abstract

In this study, blends of high-density polyethylene (HDPE) and low-density polyethylene (LDPE) were comprehensively characterized to evaluate their suitability for industrial applications. Structural, mechanical, thermal, and surface analyses were performed to determine the influence of blend composition. The results showed that the 60/40 (HDPE/LDPE) blend exhibited superior mechanical performance, including tensile strength, impact resistance, and hardness, while the 80/20 blend demonstrated higher thermal stability and morphological uniformity. The results obtained demonstrate the potential for using HDPE/LDPE blends in many areas, including packaging, insulation, and engineering products that require a balance between durability and thermal stability. They also suggest their potential future application in agricultural irrigation pipes, which require highly reliable mechanical and thermal properties over the long term.
