Ravago Mafill PP-CR CE 5041: 50% Glass-Fiber Reinforced Polypropylene
Ravago Mafill PP-CR CE 5041 is a high-performance, specialized polypropylene copolymer (PP-C) compound manufactured by Ravago. It is a highly-engineered, reinforced material containing 50% long-glass fiber (GF), designed for injection molding of demanding structural components. The high glass content provides an exceptional increase in mechanical properties, making it an ideal choice for applications that require a robust balance of high stiffness, strength, and dimensional stability. This material is a prime candidate for metal replacement and is particularly well-suited for parts subjected to high static or dynamic loads.
Key Features & Benefits
- Exceptional Stiffness: The 50% glass-fiber reinforcement provides a massive increase in flexural modulus, offering superior rigidity for structural parts.
- High Tensile & Flexural Strength: Delivers outstanding strength properties, allowing for the design of components that can withstand significant mechanical stress.
- Excellent Dimensional Stability: The high filler content minimizes warpage and shrinkage, ensuring precise part dimensions and a high degree of consistency.
- Good Heat Resistance: Maintains mechanical properties at elevated temperatures, with a high heat deflection temperature (HDT), making it suitable for under-the-hood or other high-heat applications.
- Fatigue & Creep Resistance: The long-glass fibers provide enhanced resistance to fatigue and creep, ensuring long-term performance under continuous load.
- Weight Reduction: Offers a significant weight advantage over traditional metal parts, contributing to improved fuel efficiency in automotive applications.
Typical Applications
Due to its high mechanical performance, Ravago Mafill PP-CR CE 5041 is highly recommended for structural and load-bearing components across various industries:
- Automotive: Instrument panel carriers, front-end modules, door modules, brackets, and other under-the-hood components.
- Industrial: Power tool housings, furniture components, and mechanical parts requiring high rigidity and strength.
- Appliances: Structural frames, chassis, and load-bearing parts in appliances.
Typical Properties (Representative Values)
Please note that specific values may vary slightly depending on the exact production batch and testing conditions. Always refer to the official Technical Data Sheet (TDS) from Ravago for the most accurate and up-to-date information.
Processing Guidelines (General Injection Molding)
- Drying: Pre-drying is recommended at 80°C for 2-4 hours to prevent moisture-related defects.
- Melt Temperature: 220 – 250 °C. The high glass content requires a higher melt temperature than un-filled PP.
- Mold Temperature: 40 – 80 °C.
- Injection Speed: Use a moderate to high injection speed to ensure good mold filling.
- Screw: A non-return valve and wear-resistant screw and barrel are recommended due to the abrasive nature of glass fibers.
Packaging & Storage
Ravago Mafill PP-CR CE 5041 is typically supplied in 25 kg bags or bulk containers. For optimal product quality, store in a dry, cool, and well-ventilated area, away from direct sunlight and heat sources. Keep packaging sealed until ready for use.
