Sabic QR6711K Random Copolymer PP Resin

Physical Properties

• Density: Measured using injection – molded samples according to ASTM D792, the density is 0.905 g/cc (0.0327 lb/in³), which is an indicator of its mass per unit volume.
• Melt Flow: As per ASTM D1238 standards, under a load of 2.16 kg (4.76 lb) at 230 °C (446 °F), the melt flow rate is 45 g/10 min, reflecting its flow behavior during processing.

Polymer Properties:

1. Base Material: Polypropylene (PP)
2. Key Features & Characteristic:
   
   • Exceptional Transparency and Clarity: This material offers a superior, crystal-clear appearance, which is crucial for applications where visual appeal and product visibility are key.
   • Low Stress Whitening: It is formulated to resist stress whitening, meaning it maintains its transparent appearance even when bent or stressed, a valuable characteristic for packaging and containers.
   • Good Stiffness and Heat Resistance: The material provides a good balance of rigidity and heat resistance. 
   • Excellent Processability: With a medium melt flow rate, this grade is easy to process on standard thermoforming and extrusion equipment, allowing for the production of consistent, high-quality products.

Applications:

The combination of excellent transparency, low stress whitening, and good heat resistance makes SABIC QR6711K ideal for a variety of clear, thermoformed, and extruded products.

• Food containers and trays: Perfect for transparent food packaging that requires a clear, glossy look and the ability to withstand heat for hot-fill or microwaveable use.
• Transparent cups: Its clarity and resistance to stress whitening make it a great choice for clear drinking cups.
• Household goods: Suitable for clear storage boxes and other consumer products where visibility and durability are desired.
• Medical and laboratory equipment: Its clarity and heat resistance make it a good material for medical syringes, petri dishes, and other lab items.
