PP Random Copolymer – Moplen-RP242G

Moplen RP242G, a premium random copolymer polypropylene (PP) resin from LyondellBasell, is specifically engineered for injection molding applications where exceptional clarity, gloss, and aesthetic appeal are paramount. This high-flow grade offers a superior balance of optical properties, processability, and balanced mechanical characteristics, making it an ideal choice for transparent consumer and packaging products.

Leveraging LyondellBasell’s advanced polymerization technology, Moplen RP242G ensures consistent quality and performance. Its optimized formulation provides excellent melt flow, enabling fast cycle times and the production of intricate, clear parts with superior surface finishes, enhancing both 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.
• High Flow & Excellent Processability: With a high Melt Flow Rate, RP242G facilitates rapid mold filling, reducing injection pressures and enabling fast cycle times for complex and thin-walled designs.
• Good Balance of Properties: Offers a harmonious combination of flexibility, impact strength (better than homopolymers), and rigidity, making parts durable yet aesthetically pleasing.
• Good Heat Sealability: Beneficial for packaging applications that require efficient and strong heat seals at lower temperatures.
• Good Organoleptic Properties: Low taste and odor transfer, making it highly suitable for sensitive applications such as food and beverage contact.
• Good Chemical Resistance: Inherently resistant to a wide range of chemicals, common for polypropylene.

Typical Applications:

Moplen RP242G 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.
• Blow Molded Bottles: Clear bottles for various liquids, enhancing product presentation.
• CD/DVD Cases: Providing a clear, protective casing.
• Medical Applications: Syringes, clear components for medical devices, where transparency and cleanliness are important.
• Caps and Closures: For clear bottles and jars.

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 LyondellBasell for the most accurate and up-to-date information for this specific grade.

• Melt Flow Rate (MFR) (230°C / 2.16 kg): ~25 g/10 min (ISO 1133)
• Density: ~0.90 g/cm³ (ISO 1183)
• Tensile Strength @ Yield: 25 – 30 MPa (ISO 527-1, 2)
• Flexural Modulus: 1000 – 1300 MPa (ISO 178)
• Notched Izod Impact Strength (23°C): 5.0 – 10.0 kJ/m² (ISO 180/1A)
• Haze (1mm thickness): ~10 – 20 % (ASTM D1003)
• Gloss (45°): ~80 – 90 % (ASTM D2457)
• Heat Deflection Temperature (HDT) (1.8 MPa): ~80 – 90 °C (ISO 75-2)
• Vicat Softening Temperature (A/50): ~125 – 130 °C (ISO 306)

Processing Guidelines (Injection Molding – General):

• 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: High, to ensure rapid mold filling and excellent part aesthetics, especially for thin-walled components.
• Holding Pressure: Optimized to prevent sink marks and ensure dimensional accuracy.

Packaging & Storage:

Moplen RP242G is typically supplied in 25 kg bags or bulk containers. For optimal product quality and to prevent contamination, store in a dry, cool, and well-ventilated area, away from direct sunlight and heat sources. Keep packaging sealed until ready for use.
