As a specialized manufacturer of high-performance plastic compounds, Shanghai Wenqin Plastics Co., Ltd. introduces our PC Molding Compound 121R-111, engineered to meet stringent safety and reliability requirements in demanding applications. Established in 2020 and operating from our facility in Shanghai, we combine precise formulation technology with a robust ISO9001 quality management system to deliver materials that perform consistently under challenging conditions. This compound is specifically designed to provide superior flame retardancy without compromising the inherent advantages of polycarbonate, such as impact resistance and dimensional stability.
The core value of 121R-111 lies in its certified UL94 V-0 flame retardant rating, a critical specification for components used in electronics, automotive, and industrial equipment where fire safety is paramount. This achievement allows our clients to design products that comply with international safety standards, enhancing market acceptance and reducing liability risks. Our compound is not just about meeting a rating; it's about providing a balanced material that maintains good processability, mechanical properties, and long-term performance.
Key Characteristics & Technical Advantages:
- High Flame Retardancy: The V-0 rating indicates that the material stops burning within 10 seconds after ignition and does not produce flaming drips that could ignite other materials. This is achieved through a carefully optimized additive system.
-
Retained PC Properties: Despite the flame retardant additives, the compound preserves key polycarbonate benefits:
- Excellent impact strength and toughness
- Good thermal resistance for applications up to moderate temperatures
- High dimensional stability and low creep
- Transparency options available upon request
- Enhanced Processing Stability: The formulation is designed for smooth injection molding, with consistent melt flow and reduced risk of degradation during processing, leading to higher yield rates and lower production waste.
- Broad Application Compatibility: Suitable for molding complex geometries and thin-walled parts commonly required in electrical housings, connectors, and automotive interior components.

Frequently Asked Questions (FAQ):
-
Q: Is the V-0 rating certified by a third party?
A: The compound is formulated to meet the UL94 V-0 standard. Specific certification for a final molded part depends on the testing of the finished product according to applicable procedures. We provide material data supporting this performance. -
Q: Can the color of this compound be customized?
A: Yes. While standard colors are available, we offer color customization to match your product specifications. This is a common service we provide to our clients in automotive and consumer electronics. -
Q: How does this flame retardant PC compare to standard PC in terms of mechanical properties?
A: Our 121R-111 formulation aims to minimize the trade-off. Key properties like impact strength and tensile modulus are maintained within a functional range for target applications, as shown in our technical data. -
Q: What is the recommended drying procedure before molding?
A: To ensure optimal processing, we recommend drying at 100-110°C for 3-4 hours. Specific guidelines are provided with the material shipment. -
Q: Is this material suitable for outdoor applications?
A: PC has inherent UV resistance. However, for long-term outdoor use with flame retardancy requirements, we recommend consulting our technical team for potential additive adjustments or evaluating our specific outdoor-grade options. -
Q: What is the typical lead time and packaging?
A: Standard orders are typically packaged in 25kg bags and lead times depend on order volume. We ship globally from Shanghai and Ningbo ports, with experience serving markets from North America to Southeast Asia. -
Q: Can you provide material for trial molding?
A: Yes, sample quantities are available upon request for evaluation and process testing. -
Q: Does the flame retardant property affect recyclability?
A: Like many engineered compounds, recycling considerations are specific. We recommend consulting local recycling guidelines. The material can be processed within standard polymer recycling streams under controlled conditions.
