LLDPE ExxonMobil LL6201RQ
LLDPE ExxonMobil LL6201RQ Resin
Material Introduction: LLDPE ExxonMobil LL6201RQ is linear low‑density polyethylene resin. Featured with high flowability and good blend compatibility, it is widely applied in modification processing and specific injection‑molding fields.
Main Applications
Injection Molding: large‑size household utensils such as waste bins, lids and containers.
Masterbatch Carrier: high flowability makes it ideal base resin for color masterbatch and additive masterbatch.
Film Application: referenced for film‑grade articles; verify grade property before practical use.
Other applications: bottle caps, door mats and cable compounds benefiting from favorable electrical insulation performance.
Main Properties
| Performance Category | Test Item | Test Method / Condition | Reference Data / Unit | Remarks & Interpretation |
|---|---|---|---|---|
| Basic Properties | Density | ASTM D‑1505 | 0.924‑0.936 g/cm³ | Typical LLDPE density range; minor deviation among different data sources. |
| Melt Flow Rate (MFR) | ASTM D‑1238 (190°C/2.16kg) | 20‑50 g/10min | Outstanding high flowability facilitates injection molding and fast cavity filling. Significant data divergence from public sources; official confirmation required. | |
| Mechanical Properties | Tensile Yield Strength | ‑ | ~10 MPa | Indicator of tensile‑deformation resistance. |
| Flexural Modulus | ‑ | ~260 MPa | Characterizes material rigidity. | |
| Elongation at Break | ‑ | ~100 % | Reflects material ductility. | |
| Form & Appearance | Physical Form | ‑ | Powder or Pellet | Available in powder or pellet form, subject to different packages or variants. |
| Heat Stabilizer | ‑ | Pre‑added | Built‑in heat stabilizer improves thermal stability during processing. |
Injection‑Molding Process Parameters
| Process Parameters | Recommended Range (High‑flow LLDPE) | Remarks & Interpretation |
|---|---|---|
| Drying Treatment | Normally not required | PE moisture absorption＜0.01%. No drying needed under proper storage. Dry at 60‑70 °C for 1‑2 h as precaution if package damaged or high‑humidity environment. |
| Barrel Temperature | 160‑220 °C | Temperature rises from rear zone to front zone. Crystalline polymer; barrel temperature shall exceed melting point. For this high‑flow grade, start debugging from medium‑low temperature to prevent thermal degradation. |
| Mold Temperature | 30‑60 °C | Mold temperature affects crystallization. Higher mold temperature improves crystallinity and strength yet may increase shrinkage. |
| Injection Pressure | Medium pressure (50‑100 MPa) | High flow permits medium‑low injection pressure. Excessive pressure causes flash; adjust according to product structure and dimension. |
| Injection Speed | Medium‑high speed | High flow realizes fast filling, well‑suited for thin‑wall articles. |
| 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 | Restrain excessive shear heat generation. |
