HDPE Iran Petrochemical 62N07
HDPE Iran Petrochemical 62N07 Resin
Material Introduction: HDPE Iran Petrochemical 62N07 is a high‑density polyethylene grade. It is well‑known for high rigidity, high hardness, good toughness and excellent environmental stress‑cracking resistance, mainly applied for injection‑molded industrial components and packaging containers.
Main Applications
Industrial containers & packaging: plastic boxes, turnover boxes and other vessels, benefited from high rigidity and excellent environmental stress‑cracking resistance.
Daily‑use articles: low‑grade household goods, housings and non‑load‑bearing components.
Other applications: bottle stoppers.
Core Properties
| Performance Category | Test Item | Test Method / Condition | Value & Unit | Remarks & Interpretation |
|---|---|---|---|---|
| Basic Properties | Density | ASTM D‑1505 | 0.962 g/cm³ or 0.930 g/cm³ | Typical HDPE density range for good rigidity. Data varies among sources; refer to factory test report or latest TDS for official value. |
| Melt Flow Rate (MFR) | ASTM D‑1238 (190°C/2.16 kg) | 7.0 g/10min | Good melt flowability, suitable for injection molding. | |
| Mechanical Properties | Tensile Yield Strength | ASTM D‑638 | 30 MPa | Higher value represents better tensile‑deformation resistance. |
| Tensile Strength at Break | ASTM D‑638 | 13 MPa | Maximum stress the material can withstand before fracture. | |
| Elongation at Break | ASTM D‑638 | 350 % | Good toughness and ductility; withstand relatively large deformation without fracture. | |
| Flexural Modulus | ASTM D‑790 | 1500 MPa | Indicator of rigidity; higher value delivers better bending‑deformation resistance. | |
| Izod Notched Impact Strength (23℃) | ASTM D‑256/A | 36 J/m | Room‑temperature impact‑resistance performance. | |
| Thermal Properties | Vicat Softening Temperature | ASTM D‑1525 | 127 °C | Heat‑resistance indicator; higher temperature means better thermal stability. |
| Optical Properties | Yellow Index | DIN 6167 | ≤ 4 | Color‑stability indicator; lower value means less yellowing tendency. |
Injection‑Molding Process Parameters
| Process Parameters | Recommended Range | Remarks & Interpretation |
|---|---|---|
| Drying Treatment | Normally not required | Extremely low moisture absorption (<0.01%). No drying required under good storage. Dry at 60℃ for 1 hour to remove surface moisture if package damaged or under high‑humidity environment. |
| Barrel Temperature | 180‑230 ℃ | Wide processing window for HDPE. Melting point approx.142℃, decomposition temperature 300℃. |
| Mold Temperature | 30‑60 ℃ | Mold temperature greatly affects crystallization state of molded parts. |
| Injection Pressure | Adjust according to products | HDPE features relatively high melt viscosity and limited flow‑length ratio. Larger gates and runners shall be used to avoid short shot for thin‑wall articles. |
| Holding Pressure | 40%‑60% of injection pressure | Avoid excessive holding pressure and long holding time to reduce internal stress. |
| Screw Speed | Medium speed | Prevent excessive shear‑induced heat build‑up. |
