This grade of Linear Low-Density Polyethylene stands out due to its unique molecular structure, providing superior properties compared to traditional LDPE or HDPE resins:
Enhanced Impact Strength: Excellent resistance to cracking and stress, crucial for durable containers and industrial parts.
Superior Environmental Stress Crack Resistance (ESCR): Performs reliably in applications exposed to chemicals or weathering.
High Puncture Resistance: Ideal for producing tough packaging materials and large hollow parts.
Good Flexibility & Tear Strength: Maintains integrity during forming and in end-use, even under strain.
Low Temperature Toughness: Retains properties in colder environments.
Key technical specifications include:
| Property | Test Method | Value |
|---|---|---|
| Density | ASTM D1505 | 0.925 g/cm³ |
| Melt Flow Index (MFI) | ASTM D1238 (190°C/2.16kg) | 1.0 g/10 min |
| Tensile Strength at Yield | ASTM D638 | 14 MPa |
| Elongation at Break | ASTM D638 | 800% |
| Vicat Softening Point | ASTM D1525 | 98°C |
Manufacturers benefit from:
Consistent Melt Flow: Ensures uniform wall thickness distribution in blow molded parts.
Excellent Parison Control: Provides stability during extrusion and blowing stages.
Reduced Energy Consumption: Processes efficiently at optimal temperatures.
Minimal Gel Formation: Results in smooth surface finishes on finished products.
Good Compatibility: Can be blended with other polyethylenes for specific property adjustments.
