As a specialized supplier and processor of engineering plastics, Shanghai Yunshan Plasticizing Co., Ltd. is proud to offer SABIC PC Granules 124R, a premier high-flow polycarbonate resin engineered for demanding thin-wall applications. Our direct partnership with leading material producers allows us to provide consistent, high-quality raw materials that empower manufacturers to achieve superior part quality, enhance production efficiency, and reduce cycle times. This grade is specifically formulated to address the challenges of molding complex, thin-walled components without compromising on mechanical performance.
In today's competitive manufacturing landscape, producing lightweight yet durable components is crucial. SABIC 124R PC Granules provide a reliable solution, enabling designers and engineers to push the boundaries of part design. The exceptional flow characteristics of this material facilitate the filling of intricate molds, resulting in precise replication of fine details and excellent surface finishes. This translates directly into higher yields and reduced waste for our clients.
Core Technical Advantages & Specifications:
Superior Flow for Thin Walls: The high melt flow rate (MFR) is the defining feature of 124R, allowing it to fill long, complex flow paths and ultra-thin sections that standard PC grades cannot. This enables the production of larger or more intricate parts with wall thicknesses previously unattainable.
Balanced Mechanical Properties: Despite its high flow, this grade retains the essential properties that make polycarbonate famous:
High impact strength and toughness
Good dimensional stability
Transparency (in natural form)
Heat resistance
Enhanced Processing Efficiency: Lower required injection pressure and temperature can lead to:
Reduced cycle times
Lower energy consumption
Extended tool life
Reduced molded-in stress
Typical Properties Table (Representative Values):

Frequently Asked Questions (FAQ):
Q: What is the main advantage of using a "high flow" grade like 124R over a standard PC?
A: The primary advantage is its ability to fill extremely thin and complex mold cavities at lower injection pressures. This reduces cycle times, lowers energy consumption, minimizes molded-in stress, and allows for the production of parts that are difficult or impossible to mold with standard-flow materials.Q: Does the high flow rate compromise the impact strength or heat resistance of the PC?
A: SABIC 124R is engineered to maintain a strong balance. While some trade-offs exist compared to lower-flow, high-viscosity PC grades, it retains very good impact strength and heat resistance suitable for most thin-wall applications, such as consumer electronics and automotive interiors.Q: Is this material suitable for food contact or medical applications?
A: The base polymer may have compliant formulations, but specific compliance (e.g., FDA, EU, USP Class VI) depends on the exact grade and additives. Compliance certificates are available upon request for specific product variants. Always verify the regulatory status for your intended application.Q: What are the recommended drying conditions before processing?
A: Polycarbonate is hygroscopic and must be thoroughly dried. Typical recommendations are 4-6 hours at 120°C in a desiccant dryer to achieve a moisture content below 0.02%. Inadequate drying can cause splay marks and reduce molecular weight, affecting final properties.Q: Can SABIC 124R be colored or compounded with additives?
A: Yes. The natural granules are highly suitable for coloring with masterbatches. It can also be compounded with various additives such as UV stabilizers, flame retardants (for specific grades), and anti-static agents. Custom compounding services can be discussed based on volume.Q: What injection molding machine specifications are ideal for this grade?
A: A general-purpose screw with an L/D ratio of 18:1 to 22:1 and a compression ratio of 2.0 to 2.5 is suitable. A shut-off nozzle is recommended to prevent drool. Melt temperatures typically range from 280°C to 320°C, with mold temperatures between 80°C and 100°C for optimal results.Q: How does the cost compare to standard PC grades?
A: High-flow engineering grades often command a slight premium due to their specialized performance. However, the total cost-in-use can be lower due to increased productivity (faster cycles, higher yield), energy savings, and the ability to design more efficient, lighter parts.Q: Do you provide technical data sheets and processing guides?
A: Absolutely. We provide comprehensive technical data sheets (TDS) and material safety data sheets (MSDS) for all our materials. Detailed processing guides with recommended settings for various machine types are also available from our technical support team.
