Description
🔷 Comprehensive Introduction to HDPE HBM 4265
HDPE HBM 4265 is one of the most powerful high-density polyethylene grades produced by AryaSasol Polymer Company, specifically designed for manufacturing IBCs, large agricultural tanks, small to large jerrycans, and heavy blow-molded parts. This grade is produced under Basell license and, due to its high molecular weight and broad molecular weight distribution, offers exceptional chemical and mechanical strength.
🌟 Key Features of HDPE HBM 4265
Based on the datasheet
🔹 1. Very High Creep Strength
This feature is critical for IBCs and tanks used for hazardous materials, preventing body deformation under long-term load.
🔹 2. Excellent Environmental Stress Crack Resistance (ESCR)
The presence of 1-hexene comonomer results in better structure and controlled flexibility in the polymer network, providing high resistance to chemicals, detergents, acids, and long-term stress exposure.
🔹 3. Outstanding Impact Strength Even at Low Temperatures
The value of 160 kJ/m² in the Notched Tensile Impact test at −30°C shows that this grade is suitable for cold climates and harsh loading conditions.
🔹 4. Easy Processability
HBM 4265 offers good flow and excellent melt stability, making it highly efficient for extrusion blow molding of thick-walled parts.
