Borouge RJ768MO: Random Copolymer PP for Injection Molding
Borouge RJ768MO is a premium random copolymer polypropylene (PP) resin, manufactured by Borouge, specifically engineered for injection molding applications where excellent clarity, gloss, and aesthetic appeal are paramount. This medium-flow grade is designed to provide a superb balance of optical properties, processability, and balanced mechanical characteristics, making it an ideal choice for transparent consumer and packaging products.
Utilizing Borouge’s proprietary Borstar® technology, RJ768MO offers consistent quality and performance. Its optimized formulation provides excellent melt flow, enabling efficient molding of intricate, clear parts with superior surface finishes, which enhances both manufacturing productivity and product presentation.
Key Features & Benefits
- Exceptional Clarity & Gloss: Delivers high transparency and a brilliant, shiny surface finish, significantly enhancing product visibility and overall aesthetic appeal.
- Good Flow & Processability: With a moderate Melt Flow Rate, RJ768MO allows for efficient molding of a wide range of parts, from thin-walled containers to more substantial articles.
- Good Balance of Properties: Offers a harmonious combination of flexibility, good impact resistance (better than homopolymers), and rigidity, making parts durable yet aesthetically pleasing.
- Good Organoleptic Properties: Engineered for low taste and odor transfer, making it highly suitable for sensitive applications such as food and beverage contact.
- Good Heat Sealability: Beneficial for packaging applications that require efficient and strong heat seals at lower temperatures.
- Good Chemical Resistance: Inherently resistant to a wide range of chemicals, making it a reliable choice for various packaging applications.
Typical Applications
Borouge RJ768MO is highly recommended for injection molding processes where transparency and aesthetics are key, across various industrial, consumer, and packaging sectors:
- Transparent Containers: Food storage containers, cosmetic jars, and other clear packaging where contents need to be visible.
- Housewares: Transparent storage boxes, kitchenware, and other household items where clarity is desired.
- Thin-Wall Packaging: Clear thin-walled containers for dairy, deli, and other food products.
- CD/DVD Cases: Providing a clear, protective casing with a high-gloss finish.
- Medical Applications: Syringes, clear components for medical devices, where transparency and cleanliness are important.
- Caps and Closures: For clear bottles and jars where a matching, transparent closure is needed.
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 polypropylene. However, proper storage to prevent moisture absorption is recommended.
- Melt Temperature: 200 – 240 °C (optimize based on machine type, mold design, and part thickness).
- Mold Temperature: 20 – 50 °C (higher mold temperatures can improve surface finish and reduce internal stress, particularly for optical clarity).
- Injection Speed: Medium to high, to ensure good mold filling and excellent part aesthetics.
- Holding Pressure: Optimized to prevent sink marks and ensure dimensional accuracy.
Packaging & Storage
Borouge RJ768MO 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.
