SABIC P4808NA HDPE Multimodal Resin

Physical Properties

• Density: In accordance with the ASTM D1505 standard, the density is 0.949 g/cc (0.0343 lb/in³). It affects the material’s physical and chemical behavior in non – pressure pipe applications.
• Oxidative Induction Time (OIT): Following the EN 728 standard, at 210 °C (410 °F), the OIT is ≥ 20 minutes. This shows good resistance to oxidative aging.
• Melt Flow: Tested by the ISO 1133 standard at 190 °C (374 °F), it’s 0.23 g/10 min at a 5.00 kg load and 6.5 g/10 min at a 21.6 kg load. These values help optimize the extrusion process.

Polymer Properties:

• Base Material: High Density Polyethylene (HDPE)
• Key Features:
  
  • Superior Long-Term Hydrostatic Strength: This is the most critical property for pressure pipe materials.
  • High Resistance to Rapid Crack Propagation (RCP): The multimodal structure gives the material a high resistance to fast-moving cracks, a crucial safety feature for gas and water pipes.
  • Excellent Stress Crack Resistance: This grade provides superior resistance to environmental stress cracking, protecting pipes from failure caused by external factors like soil stress or exposure to chemicals.
