Borouge BorPure™ MB6562: Bimodal HDPE for High-Performance Caps & Closures
Borouge BorPure™ MB6562 is a high-performance, bimodal high-density polyethylene (HDPE) resin, expertly manufactured by Borouge, specifically engineered for injection and compression molding. This grade is a leading choice for the caps and closures market, where an exceptional balance of organoleptic properties, environmental stress crack resistance (ESCR), and superior processability is crucial.
Using Borouge’s proprietary Borstar® technology, BorPure™ MB6562 delivers a unique combination of high-density stiffness with a broad molecular weight distribution. This ensures finished products that are not only durable and reliable but also offer a smooth and consistent user experience, making it the ideal material for a wide range of beverage and industrial caps.
Key Features & Benefits
- Excellent Organoleptic Properties: Engineered to be taste and odor-neutral, ensuring the original flavor of the packaged beverage or food product is preserved.
- Superior Environmental Stress Crack Resistance (ESCR): The bimodal structure provides outstanding resistance to slow crack growth, guaranteeing the long-term integrity and sealing performance of caps and closures.
- Optimized Flow & Processability: With a Melt Flow Rate of 1.5 g/10min, this grade offers excellent flow properties for high-speed injection and compression molding, enabling fast cycle times and efficient production.
- Controlled Opening Torque: Contains a slip agent to provide a consistent and easy opening and closing experience for consumers, a critical feature for carbonated soft drink caps.
- Good Impact Strength: Provides durability and resistance to breakage, ensuring closures remain intact during bottling, transport, and use.
- Lightweighting Potential: The resin’s strength allows for the design of lighter caps and closures, leading to material reduction and cost savings without compromising on performance.
Typical Applications
Borouge BorPure™ MB6562 is highly recommended for molding processes focused on producing high-quality components for the packaging industry:
- Caps and Closures: For carbonated soft drinks, bottled water, juices, and other beverages.
- Consumer & Industrial Articles: Components requiring a combination of high ESCR and durability.
- Thin-Walled Containers: Injection molded containers where a good balance of stiffness and toughness is required.
Typical Properties (Representative Values)
Please note that specific values may vary slightly depending on the exact production batch and testing conditions. Always refer to the official Technical Data Sheet (TDS) from Borouge for the most accurate and up-to-date information for this specific grade.
Processing Guidelines (General Injection & Compression Molding)
- Drying: Generally not required for polyethylene. Proper storage is recommended to prevent moisture absorption.
- Melt Temperature: 190 – 250 °C (optimize based on machine type, mold design, and part thickness).
- Mold Temperature: 10 – 40 °C.
- Injection Speed: As high as possible to ensure good mold filling.
Packaging & Storage
Borouge BorPure™ MB6562 is typically supplied in 25 kg bags or bulk containers. For optimal product quality, store in a dry, cool, and well-ventilated area, away from direct sunlight and heat sources. Keep packaging sealed until ready for use.
