RP348N

Moplen RP348N, a premium random copolymer polypropylene (PP) resin from LyondellBasell, is specifically engineered for blow molding and extrusion applications where exceptional clarity, gloss, and aesthetic appeal are paramount. This low-to-medium flow grade offers an outstanding balance of optical properties, good melt strength, and balanced mechanical characteristics, making it an ideal choice for transparent packaging and demanding sheet applications.

Leveraging LyondellBasell’s advanced polymerization technology, Moplen RP348N ensures consistent quality and performance. Its optimized formulation provides excellent melt strength and stable processing, enabling manufacturers to produce high-quality, transparent articles such as bottles and thermoformed containers 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.
• Good Melt Strength: Crucial for stable parison formation in blow molding and consistent sheet/film extrusion, ensuring efficient and reliable processing.
• Balanced Mechanical Properties: Offers a harmonious combination of flexibility, good impact resistance (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 such as food and beverage contact.
• Good Chemical Resistance: Inherently resistant to a wide range of chemicals, common for polypropylene.

Typical Applications:

Moplen RP348N is highly recommended for blow molding, extrusion, and certain injection molding processes where transparency and aesthetics are key:

• Blow Molded Bottles: Clear bottles for water, juices, edible oils, detergents, shampoos, personal care products, and other liquid packaging.
• Extruded Sheet: For subsequent thermoforming of clear cups, containers, trays, and blister packaging.
• Cast Films (CPP): For high-clarity flexible packaging films, lamination films, and textile packaging.
• Transparent Containers: Injection molded thick-walled containers where clarity and a balance of properties are desired.
• Medical Applications: Clear bottles and components for pharmaceutical and healthcare uses.

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): ~8 g/10 min (ISO 1133)
• Density: ~0.90 g/cm³ (ISO 1183)
• Tensile Strength @ Yield: 20 – 25 MPa (ISO 527-1, 2)
• Flexural Modulus: 800 – 1100 MPa (ISO 178)
• Notched Izod Impact Strength (23°C): 6.0 – 12.0 kJ/m² (ISO 180/1A)

Processing Guidelines (General):

• Drying: Generally not required for polypropylene. However, proper storage to prevent moisture absorption is recommended.
• Melt Temperature: 200 – 240 °C (optimize based on equipment type, mold/die design, and desired product thickness).
• Die/Mold Temperature:
  • Blow Molding: Varies depending on equipment, usually 20-50 °C for molds.
  • Extrusion (Film/Sheet): Roll temperatures typically 20-50 °C for chilling/clarity.
  • Injection Molding: 20-50 °C for molds (higher for clarity).
• Specific Process Settings: Optimize for parison control (blow molding), take-off speed (extrusion), and general part quality.

Packaging & Storage:

Moplen RP348N 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.
