OPaL PPCP Opalene MI15
OPaL Opalene MI15 is a heterophasic polypropylene block copolymer (PPCP) engineered via Ineos gas-phase technology for demanding automotive exterior applications. MI15 delivers very high impact resistance, balanced stiffness, and high flow for easy processing—making it ideal for bumper fascia, air dams, exterior trim, and other high-impact auto parts. Its natural colour, anti-gas fading properties, and IS 10910 compliance add to its appeal for OEMs and Tier-1 suppliers in India. MI15 is optimized for fast cycles, complex moulds, and long-term durability in automotive environments.
Specifications
Physical Properties
- Melt Flow Index: 15 g/10 min (230°C/2.16 kg) – high flow for complex, thin-wall auto parts
- Density:90 g/cm³ – lightweight for automotive and exterior use
Mechanical Properties
- Tensile Strength at Yield: ~27 MPa – robust for structural and exterior applications
- Flexural Modulus: ~1200–1300 MPa – balanced stiffness for dimensional stability
- Notched Izod Impact (23°C): ~150+ J/m – very high impact for crash and drop resistance
Key Technical Insights
- Heterophasic morphology: Ensures toughness and low-temperature impact resistance
- Anti-gas fading: Maintains colour and properties under UV and exhaust exposure
- IS 10910 compliance: Suitable for food/pharma contact if required by the application
Automotive Applications
Opalene MI15 is purpose-built for automotive exterior parts where impact resistance and stiffness are non-negotiable. Its high MFI enables fast, uniform mould filling—crucial for large, complex bumper fascia and air dams. The grade’s toughness protects against low-temperature impacts, while its anti-gas fading ensures long-term colour and property retention in exposed environments. MI15 is also used for exterior trims and technical parts where both mechanical and cosmetic performance are essential. Its compliance with IS 10910 makes it a reliable choice for applications that may require regulatory documentation.
Processing
- Barrel temperature: 180–240°C
- Mould temperature: 30–50°C
- Processing tips: High flow supports thin-wall and multi-cavity tools; optimize packing and cooling for best surface finish and dimensional accuracy
- Cycle time: Fast cycles possible with proper mould and machine setup
Deep Technical Insights
- Ineos gas-phase technology: Delivers reproducible heterophasic morphology for superior impact and stiffness
- Anti-gas fading: Prevents property loss and yellowing from exhaust/UV exposure
- OEM suitability: Balanced properties and compliance position MI15 as a strong candidate for automotive approval and use in global supply chains
