Borouge BorPure™ MB5569 is a high-performance bimodal high-density polyethylene (HDPE) resin, manufactured by Borouge, specifically engineered for injection molding applications. This grade is a leading material for caps and closures, offering a unique combination of high stress crack resistance (ESCR), excellent organoleptic properties, and a melt flow rate optimized for high-speed production.
Utilizing Borouge’s proprietary Borstar® technology, BorPure™ MB5569 delivers a unique molecular structure that provides an exceptional balance of stiffness and toughness. This ensures finished products that are not only durable and reliable but also preserve the integrity of the packaged product while allowing for efficient and high-volume manufacturing.
Key Features & Benefits
- Excellent Organoleptic Properties: Engineered to be taste and odor-neutral, which is crucial for preserving the original flavor of the packaged beverage or food product.
- Superior Environmental Stress Crack Resistance (ESCR): The bimodal structure provides outstanding resistance to stress cracking, guaranteeing the long-term sealing performance of caps and closures, particularly for carbonated drinks.
- Optimized Flow & Processability: With a moderate Melt Flow Rate, this grade offers excellent flow properties for efficient, high-speed injection molding, supporting fast cycle times and high output.
- Good Impact Strength: Provides durability and resistance to breakage, ensuring closures remain secure and intact throughout the supply chain and during consumer use.
- Lightweighting Potential: The resin’s high strength-to-weight ratio allows for the design of lighter, thinner-walled closures, leading to material reduction and cost savings without compromising performance.
- Good Colorability: Its natural pellet form allows for easy coloring to meet a wide range of aesthetic requirements.
Typical Applications
Borouge BorPure™ MB5569 is highly recommended for molding processes for high-quality packaging components, including:
- Caps and Closures: For carbonated soft drinks, bottled water, juices, and other beverages.
- Consumer & Industrial Articles: Components requiring a balance of high ESCR and durability.
- Thin-Walled Containers: Injection molded containers where a good combination 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.
Processing Guidelines (General Injection 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: Use a high injection speed to ensure good mold filling, particularly for thin-walled sections.
Packaging & Storage
Borouge BorPure™ MB5569 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.
