HDPE Qatar Chemical Q50100
HDPE Qatar Chemical Q50100 Resin
Material Introduction: HDPE Qatar Chemical Q50100 is a high‑density polyethylene supplied as non‑toxic, tasteless and odorless milky‑white pellets. It is well‑known for good rigidity, excellent environmental stress‑cracking resistance and outstanding low‑temperature impact strength.
Main Applications
Large‑size industrial containers: 220‑L shipping drums, agro‑chemical containers, gasoline tanks, truck bed liners.
Other blow‑molded articles: formwork panels and large‑size structural parts.
Performance Parameters
| Performance Category | Test Item | Test Method / Condition | Value & Unit | Remarks & Interpretation |
|---|---|---|---|---|
| Basic Properties | Density | ASTM D‑1505 | 0.948 g/cm³ | HDPE grade with high hardness and good rigidity. |
| Melt Flow Rate (MFR) | ASTM D‑1238 (190°C/2.16 kg) | 0.06 g/10min | Low MFR delivers high melt strength, ideal for blow‑molding to stabilize parison profile. | |
| High‑Load Melt Index (HLMI) | ASTM D‑1238 (190°C/21.6 kg) | 9‑10 g/10min | Flow property under high load; slight deviations exist among different data sources. | |
| Mechanical Properties | Tensile Yield Strength | ASTM D‑638 (50 mm/min) | 26 MPa | Resistance capacity against tensile deformation. |
| Elongation at Break | ASTM D‑638 (50 mm/min) | ＞600 % | Superb toughness and ductility; withstand heavy deformation without fracture. | |
| Flexural Modulus | ASTM D‑790 | 1170 MPa | Indicator of rigidity; higher value represents better bending‑deformation resistance. | |
| Shore D Hardness | ASTM D‑2240 | 62 | Provides certain surface scratch‑resistance. | |
| Environmental Stress‑Cracking Resistance (ESCR) | Condition A/B, F50, 100% Igepal, ASTM D‑1693 | ＞600 h | Extremely excellent ESCR, core advantage for chemical and detergent containers. | |
| Thermal Properties | Brittleness Temperature | ASTM D‑746 | ＜‑75 °C | Outstanding low‑temperature toughness. |
Blow‑Molding Processing
For hollow blow‑molding, temperature, pressure and other parameters shall be optimized according to equipment, container volume and performance requirements.
‑ Barrel rear zone temperature：130‑180°C ‑ Barrel front zone temperature：180‑220°C ‑ Die‑head temperature：170‑210°C ‑ Cooling method：in‑mold cooling ‑ Parison control: low melt index (0.06 g/10min) provides high melt strength to prevent parison sagging.
Processing Notes
- Melt strength: Low MFR offers good melt strength and keeps parison stable during blow‑molding.
- ESCR performance: >600‑hour ESCR enables the material to resist stress cracking under chemical contact, suitable for chemical and detergent packaging.
- Shrinkage: HDPE features relatively large and directional shrinkage which may cause warpage. Maintain uniform and stable cooling and reasonable mold‑temperature control.
