As a specialized manufacturer and supplier, Shanghai Yunshan Plasticizing Co., Ltd. is pleased to introduce our premium PC Makrolon 2807 Polycarbonate Resin. Sourced from leading raw material channels and processed with stringent quality control in our Shanghai facility, this high-flow grade resin is engineered specifically to meet the demanding requirements of modern injection molding processes. We understand that production efficiency and part quality are paramount for our B2B clients, which is why we offer this material designed to fill complex, thin-walled molds effortlessly while maintaining excellent mechanical properties.
This product is formulated to address common challenges in injection molding, such as reducing cycle times and minimizing defects. Its superior flow characteristics enable manufacturers to achieve consistent results even in intricate part geometries, potentially lowering operational costs and enhancing productivity.
Detailed Product Features and Technical Advantages:
The core value of Makrolon 2807 lies in its optimized balance between processability and performance. Below are its key characteristics:
Exceptional Flow Properties: The high melt flow rate (MFR) is the defining feature, allowing the resin to fill molds quickly and completely, which is critical for producing thin-walled components or parts with long flow paths.
High Impact Strength: Despite its excellent flow, it retains the renowned toughness of polycarbonate, providing good resistance to impact and mechanical stress in the final product.
Good Dimensional Stability: Parts molded from this resin exhibit low shrinkage and warpage, ensuring precise tolerances and fit in assembled applications.
Clarity and Surface Finish: It offers the potential for high optical clarity and a glossy surface finish, suitable for applications where aesthetics are important.
Thermal Resistance: It maintains good performance across a range of temperatures, making it suitable for applications that experience thermal cycling.
Technical Specifications Overview:
| Property | Typical Value / Description | Benefit to Customer |
|---|---|---|
| Melt Flow Rate (MFR) | High Flow Grade (Specific value available upon request) | Enables faster filling, lower injection pressure, suitable for complex molds. |
| Density | Approx. 1.2 g/cm³ | Standard for PC, allows for accurate part weight calculation. |
| Tensile Strength | High | Provides structural integrity to molded parts. |
| Notched Izod Impact | Good | Ensures durability and resistance to cracking upon impact. |
| Heat Deflection Temperature (HDT) | Data available upon request | Indicates performance under load at elevated temperatures. |
| Processing Temperature | Recommended range provided with material data sheet | Guides optimal machine settings for consistent quality. |
Benefits for Your Business:
Increased Production Efficiency: Reduced injection pressure and faster cycle times can lead to higher output.
Lower Rejection Rates: Excellent flow reduces the risk of short shots and weld lines, improving yield.
Design Freedom: Allows engineers to design more complex and thinner parts without compromising on fillability.
Material Consistency: Supplied from a reliable source in Shanghai, we ensure batch-to-batch uniformity for stable processing.
Common Application Areas:
Consumer Electronics: Housings, covers, and transparent components for devices.
Automotive Interiors: Instrument panels, lens covers, and functional trim parts.
Electrical Components: Connectors, housings for switches, and enclosures.
Medical Devices: Housings for non-implantable equipment requiring clarity and sterilization compatibility (subject to specific grade validation).
Lighting: Diffusers, lenses, and covers for LED fixtures.

Frequently Asked Questions (FAQ):
Q1: What is the main advantage of the "High Flow Grade" in Makrolon 2807?
A: The primary advantage is its significantly enhanced melt flow during injection molding. This allows the resin to fill intricate and thin-walled cavities more easily and at lower pressures, which can result in faster cycle times, reduced energy consumption, and fewer molding defects like short shots.
Q2: Is this PC resin suitable for producing transparent parts?
A: Yes, in its natural form, Makrolon 2807 offers good clarity. It is a viable option for applications requiring transparency. For specific optical requirements or color needs, coloring compounds can be added during processing, or pre-colored grades can be inquired about.
Q3: How does the impact strength of this high-flow grade compare to standard PC grades?
A: While high-flow grades are optimized for processability, Makrolon 2807 is formulated to maintain a robust balance of properties. Its impact strength remains good and is suitable for many applications requiring toughness. For extreme impact-critical applications, consulting the detailed technical data sheet for specific Izod impact values is recommended.
Q4: Can this material be used for food contact applications?
A: The standard Makrolon 2807 grade is not specifically certified for food contact. If your application requires compliance with food contact regulations (such as FDA, EU), you must inquire about special grades or certifications, as these are subject to specific formulations and testing.
Q5: What are the recommended drying conditions before processing this PC resin?
A: Polycarbonate is hygroscopic and must be thoroughly dried before processing to prevent hydrolysis degradation, which weakens the material. Typical recommendations involve drying at 120°C for 3-4 hours to achieve a moisture content below 0.02%. Exact parameters should be verified with the provided material safety data sheet (MSDS) and processing guide.
Q6: Do you provide technical support for processing parameters?
A: Yes, as part of our service from Shanghai Yunshan Plasticizing, we can provide general guidelines for injection molding parameters such as melt temperature, mold temperature, and injection speed based on the typical behavior of this grade. For optimal results tailored to your specific mold and machine, collaborative fine-tuning is advised.
Q7: Is this material flame retardant?
A: The standard Makrolon 2807 is a general-purpose, high-flow PC resin and is not inherently flame-retardant. If flame retardancy (e.g., UL94 rating) is a requirement, we recommend inquiring about specialized flame-retardant PC grades that are available.
Q8: What packaging is available for this resin?
A: The material is typically supplied in standard packaging such as 25 kg paper bags with inner liner to ensure cleanliness and moisture protection. Other packaging options like big bags may be available upon request to suit different scales of consumption.
