SABIC BM6246LS HDPE Unimodal Resin

Physical Properties

• Density: Measured via ASTM D792, the material’s density is 0.961 g/cc (0.0347 lb/in³), indicating high rigidity for structural applications.
• ESCR 100% Igepal®: At F50 per ASTM D1693B, environmental stress crack resistance is 24 hours under 100% Igepal® concentration.
• ESCR 10% Igepal®: Under F50 (ASTM D1693B), resistance to 10% Igepal® is 16 hours, showing reduced durability at lower chemical strength.
• Melt Flow (2.16 kg): As per ASTM D1238, the rate is 0.70 g/10 min at 190 °C (374 °F) under a 2.16 kg (4.76 lb) load, suitable for low-flow processes.
• Melt Flow (5.00 kg): Under a 5.00 kg (11.0 lb) load, the rate increases to 2.5 g/10 min, reflecting improved flow with higher stress.
• Melt Flow (21.6 kg): At 21.6 kg (47.6 lb) load, the melt flow rate surges to 46 g/10 min, indicating high responsiveness to heavy loading.

Polymer Properties:

• Base Material: High Density Polyethylene (HDPE) homopolymer.
• Key Features:
  
  • Outstanding ESCR: This grade provides exceptional resistance to slow crack growth, a critical factor for the longevity of pipes.
  • Superior Hydrostatic Strength: BM6246LS is rated for high-pressure applications.
  • Optimized for Pipe Extrusion: Ideal viscosity for pipe extrusion.

Applications:

• Potable Water Pipes: The resin’s long-term hydrostatic strength and excellent ESCR make it a preferred material for potable water distribution pipes.
• Gas Distribution Pipes: Its high pressure rating and resistance to stress cracking are essential for natural gas and propane distribution networks.
• Industrial and Sewer Pipes: This grade is also widely used in industrial piping and sewer systems.
