Description
HDPE HD5218EA is a high-density polyethylene (HDPE) copolymer grade designed specifically for injection molding applications. It is characterized by its high flow rate, making it suitable for fast processing cycles and reducing molding warpage. This material is particularly well-suited for thin-wall injection molding due to its narrow molecular weight distribution, which contributes to its desirable properties such as high tensile strength, good elongation at break, and excellent impact resistance.
- Melt Flow Index (MFI): 18 g/10 min at 190°C, indicating good processability.
- Density: 0.952 g/cm³, typical for HDPE materials.
- Tensile Strength @ Yield: 26 MPa, providing robust mechanical integrity.
- Elongation @ Break: 1000%, showcasing high flexibility and ductility.
- Flexural Modulus: Not specified, but generally expected to be high for HDPE.
- Hardness Shore D: 66, indicating moderate hardness.
- Charpy Impact Resistance (Notch): 5 KJ/m², demonstrating good impact resistance.
general purpose injection molding with indoor applications.
- Housewares: Due to its aesthetic appeal and durability.
- Caps & Closures: Benefiting from its tight dimensional control and chemical resistance.
- Thin-Walled Containers: Ideal for packaging due to their lightweight and strength.
- PET Bottle Bases: Where its compatibility with PET and resistance to chemicals is advantageous.
- Food Contact: Approved for food contact applications, ensuring safety and compliance.
