LOTTE SM598 Random Copolymer PP Resin

Physical Properties

• Base Resin Density: Measured according to ASTM D1505, the base resin density is 0.900 g/cc (0.0325 lb/in³), representing the mass per unit volume of the base material.
• Water Absorption: As per ASTM D570, the water absorption is 0.020 % after a duration of 86400 seconds (24.0 hours), indicating the material’s moisture – absorbing capacity.
• Base Resin Melt Index: Based on ASTM D1238, at a temperature of 230 °C (446 °F), the base resin melt index is 30 g/10 min, reflecting the flowability of the base resin under specific processing conditions.

Polymer Properties:

1. Base Material: Polypropylene (PP)
2. Key Features & Characteristics:
   • Extremely High Flowability: Ultra-high melt flow rate ideal for filling intricate, thin-walled molds.
   • High Transparency & Gloss: Random copolymer delivers superior clarity and high-gloss finish for visual-critical applications.
   • Balanced Stiffness & Heat Resistance: Maintains rigidity and heat resistance for durable performance.
   • Low Brittleness: Stiffness-impact resistance balance reduces breakage, ensuring part durability.

Applications:

• Microwaveable lunch boxes: The material’s heat resistance and transparency are perfect for food containers that can be heated in a microwave.
• Food containers and trays: This grade is used for transparent food packaging where a clear, glossy look and durability are needed.
• Disposable tableware: The ultra-high flow rate allows for the fast production of disposable cups, containers, and cutlery, greatly improving manufacturing efficiency.
• Transparent containers: It’s suitable for various clear containers for consumer goods, offering both aesthetic appeal and functionality.
