Performance Parameters
| Performance Category | Test Item | Test Method / Condition | Value & Unit | Remarks & Interpretation |
|---|---|---|---|---|
| Basic Properties | Density | ASTM D‑1505 | 0.924 g/cm³ | Typical density range for LLDPE. |
| Melt Flow Rate (MFR) | ASTM D‑1238 (190°C/2.16kg) | 20 g/10min | High flowability, well‑suited for injection molding, easy cavity filling, ideal for thin‑wall articles. | |
| Mechanical Properties | Tensile Yield Strength | ASTM D‑638 | 12.0 MPa | Indicator of tensile‑deformation resistance. |
| Tensile Strength at Break | ASTM D‑638 | 8.50 MPa | Maximum stress the material can bear before fracture. | |
| Elongation at Break | ASTM D‑638 | 450 % | Excellent toughness and ductility, resistant to fracture under large deformation. | |
| 1% Secant Modulus | ASTM D‑638 | 315 MPa | Characterizes material rigidity. | |
| Izod Notched Impact Strength (23°C) | ASTM D‑256 | 540 J/m | Good room‑temperature impact resistance. | |
| Hardness (Shore D) | ASTM D‑2240 | 55 | Provides certain surface scratch‑resistance. | |
| ESCR (F50) | ASTM D‑1693 (100% Igepal CO‑630) | 24.0 h | Environmental‑stress‑crack‑resistance; higher value means better performance. | |
| Thermal Properties | Vicat Softening Temperature | ASTM D‑1525 | 94.0 °C | Heat‑resistance indicator. |
| Brittleness Temperature | ASTM D‑746 | ＜‑75.0 °C | Retain toughness under ultra‑low temperature with excellent low‑temperature performance. |
Injection‑Molding Process Parameters
| Process Parameters | Recommended Range | Remarks & Interpretation |
|---|---|---|
| Drying Treatment | Normally not required | PE moisture absorption ≤0.01%, drying is generally unnecessary before processing. |
| Barrel Temperature | 160‑220 °C | Crystalline polymer; barrel temperature shall be higher than melting point. General LLDPE / LDPE range:140‑200 ℃, lower for rear zone, higher for front zone. |
| Mold Temperature | 30‑60 °C | Mold temperature affects crystallization. Higher mold temperature brings higher crystallinity and strength yet larger shrinkage. Typical LDPE mold temperature:30‑45 ℃. |
| Injection Pressure | 50‑100 MPa | Low melt viscosity and good flowability permit medium‑to‑low injection pressure. Excessive pressure causes flash. Lower pressure for simple thick‑wall parts; higher pressure for complex parts. |
| Injection Speed | Medium‑high speed | High flow realizes fast filling, suitable for thin‑wall products. |
| Holding Pressure | 40%‑60% of injection pressure | Avoid excessive holding pressure and long holding time to reduce internal stress. |
| Back Pressure | 0.5‑1.5 MPa | Low back pressure for melt compaction; excessive back pressure generates extra shear heat. |
| Screw Speed | Medium speed | Prevent excessive shear heat build‑up. |
