Borouge HDPE MB9581
Product Description:
MB9581 is a high-density polyethylene (HDPE) grade from Borouge used for making caps and closures for beverages and other rigid packaging. Key features include excellent organoleptic properties, high environmental stress crack resistance (ESCR), and good flowability, making it suitable for high-speed injection and compression molding processes.
Properties:
- Excellent organoleptic properties: This means the material does not impart any taste or odor, making it ideal for packaging beverages like water, juice, and tea.
- Superior ESCR: It has excellent resistance to cracking under stress, which is crucial for bottle caps and closures.
- High flowability: The material processes easily, and despite its high MFR, it behaves like a lower MFR material, enabling efficient, high-speed production.
- Stiffness: It maintains excellent stiffness, which is important for the functionality of closures.
- Ideal for molding: It is suitable for both injection and compression molding applications.
- Bimodal properties: It is a multimodal HDPE, which provides a good balance of processability and mechanical properties, and is a migration trend for lightweight closures.
Applications:
- Closures: Ideal for caps and closures for taste-sensitive products like water, juice, and tea due to its excellent organoleptic performance
- Molding: Suitable for both injection molding and compression molding
- Packaging: Used for industrial jerry can and bottle caps and lids
