HDPE (High‑Density Polyethylene)

HDPE boasts superior rigidity, tensile strength and hardness compared with general‑purpose polyethylene with favourable mechanical strength. It combines good heat‑resistance and cold‑resistance, with service temperature reaching approximately 100 °C. Chemically, it resists corrosion from acids, alkalis and various salts, and is barely dissolved by organic solvents at room temperature. It also delivers excellent electrical insulation, zero moisture absorption and good water‑vapor barrier performance. Nevertheless, its ageing resistance and environmental‑stress‑cracking resistance are relatively insufficient. It tends to degrade under sunlight or high‑temperature exposure, and its surface gloss is inferior to polypropylene (PP).

Main Applications

Blow molding: Mass‑produced hollow containers such as shampoo bottles, pharmaceutical bottles, oil drums, cosmetic bottles, large‑size automotive fuel tanks and chemical storage tanks.

Injection molding: Turnover boxes, waste bins, pallets, daily‑use plastic articles and thin‑wall packaging containers.

Extrusion molding: Water‑supply pipes, gas pipes, drainage pipes and insulating sheaths for wires and cables.

Film & blow‑film processing: Packaging films including shopping bags, grocery bags and food‑packaging films. Such films have low permeability to water vapor and air with good moisture‑proof performance.

Please specify your additional requirements: gloss level, melt‑flow index, ash content, environmental compliance, surface pitting and other physical‑property parameters.

MOQ: 1 ton upon successful sample testing. After‑sales: return and replacement for quality‑related defects.
