Product Features of Borouge RB307MO

1. Excellent Transparency and Surface Appearance

PP RB307MO exhibits outstanding optical properties due to its fine and uniform crystalline structure. Injection-molded articles made from this grade show high transparency or semi-transparency combined with excellent surface gloss. The smooth surface finish and low haze contribute to an attractive visual appearance, making the material especially suitable for applications where product display and aesthetics are important.

2. High Flowability and Superior Processability

With a high melt flow rate of approximately 30 g/10 min (230 °C / 2.16 kg), RB307MO provides excellent flow behavior during injection molding. The resin fills mold cavities smoothly and efficiently, even in thin-wall or complex designs. This high flowability allows for reduced injection pressure, shorter cycle times, and improved productivity, particularly in high-speed and multi-cavity molding operations.

3. Balanced Stiffness and Toughness

This grade offers a well-balanced combination of stiffness and impact resistance. While optimized for transparency and processing efficiency, the material still maintains sufficient rigidity for everyday consumer and packaging products. Compared with polypropylene homopolymers, it provides improved toughness, helping to reduce the risk of brittleness or cracking during handling and normal use.

4. Good Dimensional Stability

The resin demonstrates stable and uniform shrinkage behavior during molding, resulting in low warpage and consistent part dimensions. This dimensional stability ensures good repeatability in mass production and makes RB307MO suitable for applications that require reliable size accuracy and consistent quality across production batches.

Main Applications

Due to its excellent transparency, flowability, and stable processing behavior, Borouge RB307MO is widely used in:

  • Transparent and semi-transparent food packaging containers
  • Household and daily-use items (storage boxes, cups, lids, etc.)
  • Thin-wall injection-molded products
  • Disposable and reusable consumer goods
  • Medical and laboratory disposable products (subject to regulatory compliance)

Regulatory and Safety Information

  1. RB307MO is generally not classified as a hazardous material.

  2. Suitable for food contact applications, subject to compliance with relevant local regulations (FDA, EU, GB, etc.)

  3. Free from restricted heavy metals and commonly regulated harmful substances.
