LOTTE SM498 Random Copolymer PP Resin

Physical Properties

• Base Resin Density: Measured in line with ASTM D1505, the Base Resin Density is 0.900 g/cc (0.0325 lb/in³), signifying the mass per unit volume of the base resin.
• Water Absorption: According to ASTM D570, the Water Absorption is 0.020% after 86400 sec (24.0 hours), reflecting the material’s capacity to absorb water.
• Base Resin Melt Index: As per ASTM D1238, at a temperature of 230 °C (446 °F), the Base Resin Melt Index is 20 g/10 min, which gauges the resin’s flowability under specified conditions.

Polymer Properties:

1. Base Material: Polypropylene (PP)
2. Key Features & Characteristics:
   
   • Exceptional Flowability: This grade has an ultra-high melt flow rate, making it an ideal choice for filling intricate and complex molds, especially those with thin walls.
   • High Transparency and Gloss: As a random copolymer, it offers superior clarity and a high-gloss surface finish. 
   • Good Stiffness and Heat Resistance: The material maintains a good balance of rigidity and heat resistance. 
   • Low Brittleness: It provides a good balance between stiffness and impact resistance, ensuring that finished parts are durable and less prone to breakage under normal use.

Applications:

The combination of very high flow, excellent transparency, and good heat resistance makes LOTTE SM498 a great fit for a wide range of clear, thin-walled, and heat-resistant products.

• 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, improving manufacturing efficiency.
• Transparent containers: It’s suitable for various clear containers for consumer goods, offering both aesthetic appeal and functionality.
