Key Features
Exceptional Clarity and Aesthetics
The nucleated nature of RB707CF results in a high degree of transparency and a glossy surface finish, making it an ideal choice for applications where visual appeal is paramount.
High Melt Flow Rate (MFR)
With a nominal MFR of 25 g/10 min, this grade allows for faster injection speeds, reduced cycle times, and the ability to fill complex and thin-walled mold designs.
Good Stiffness-to-Impact Balance
While offering high clarity, RB707CF maintains a favorable balance of rigidity and toughness, ensuring the durability of the final product.
Excellent Organoleptic Properties
The material is engineered to have low taste and odor transfer, a critical requirement for food and beverage containers.
Food Contact Compliance
Borouge RB707CF is formulated to comply with major international food contact regulations, including those from the U.S. Food and Drug Administration (FDA) and the European Union.

Processing Guidelines for Injection Molding
To achieve optimal results when processing Borouge RB707CF, the following injection molding parameters are recommended:
Drying
Generally not required if stored in proper conditions. If moisture absorption is suspected, drying at 80°C for 2-3 hours is recommended.
Melt Temperature
220 - 250 °C. A lower temperature within this range is often sufficient and can help to minimize cycle times.
Mold Temperature
20 - 50 °C. A higher mold temperature will enhance surface gloss and clarity.
Injection Speed
High injection speeds are recommended to take advantage of the material's high MFR.
Holding Pressure
30 - 60% of the injection pressure.
Back Pressure
Low back pressure is generally sufficient (5 - 10% of injection pressure).
Safety, Handling, and Storage
Safety
- • Refer to the official Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) for detailed safety information.
- • Under normal processing conditions, Borouge RB707CF is a safe material to handle.
- • Molten polymer can cause severe thermal burns. Appropriate personal protective equipment (PPE), including heat-resistant gloves and eye protection, should be worn when handling molten material.
- • Provide adequate ventilation in processing areas to remove any fumes that may be generated at elevated temperatures.
Handling
- • Spilled pellets can create a slip hazard. Clean up spills immediately.
- • The material is not classified as hazardous for transportation.
Storage
- • Store in a dry, cool, and well-ventilated area, away from direct sunlight and sources of heat.
- • Keep containers closed to prevent contamination and moisture absorption.
