As a specialized plastics manufacturer, Shanghai Wenqin Plastics Co., Ltd. is proud to offer the DuPont Nylon 66 Resin 70G13HS1L, a premium engineering plastic specifically engineered for high-performance, thin-wall molding applications. Established in 2020 and operating from our facility in Shanghai, we leverage our expertise to supply high-quality polymer solutions that meet the rigorous demands of modern manufacturing. This high-speed crystallization grade is designed to significantly enhance production efficiency and part quality, providing a reliable material choice for manufacturers seeking to optimize their injection molding processes.
This advanced Nylon 66 resin addresses the critical challenges associated with molding thin-walled components, where fast cycle times and excellent dimensional stability are paramount. By choosing our 70G13HS1L grade, you gain access to a material that not only speeds up your production but also delivers consistent, high-quality results batch after batch.
Key Product Features & Technical Advantages:
Exceptional Flow Characteristics: Engineered for superior melt flow, allowing it to fill intricate, thin-walled molds completely and uniformly, reducing the risk of short shots or weld lines.
Rapid Crystallization Rate: The defining property of this grade. It achieves a fast set-up time in the mold, enabling dramatically shorter cycle times compared to standard Nylon 66 grades. This translates directly to higher output and lower cost per part.
High Stiffness and Strength: Provides excellent mechanical properties, including high tensile strength and rigidity, ensuring that the final thin-walled parts are durable and can withstand functional loads.
Good Thermal and Chemical Resistance: Maintains performance over a wide temperature range and offers good resistance to many oils, fuels, and chemicals, making it suitable for demanding environments.
Excellent Dimensional Stability: Low moisture absorption and low mold shrinkage contribute to precise, stable part dimensions, which is critical for components requiring tight tolerances.
Surface Finish: Produces parts with a smooth, high-quality surface appearance, often reducing or eliminating the need for secondary finishing operations.
Technical Specifications & Typical Properties:
The following table outlines key property ranges for the DuPont Nylon 66 70G13HS1L resin. Specific values may vary based on processing conditions and part design.
| Property | Test Method | Typical Value / Range |
|---|---|---|
| Melt Flow Rate (275°C/5kg) | ISO 1133 | High (Specific data available upon request) |
| Tensile Strength | ISO 527 | 80 - 85 MPa |
| Flexural Modulus | ISO 178 | 2800 - 3200 MPa |
| Izod Impact, Notched (23°C) | ISO 180/1A | 5 - 7 kJ/m² |
| Heat Deflection Temp (1.8 MPa) | ISO 75-1/-2 | Approx. 255°C |
| Mold Shrinkage (Flow direction) | - | 1.2 - 1.8% |
| Density | ISO 1183 | ~1.14 g/cm³ |
Primary Applications & Customer Benefits:
Automotive Components: Ideal for under-hood connectors, sensor housings, and other thin-walled parts requiring heat resistance and fast cycling.
Electrical & Electronic Housings: Used for miniature connectors, circuit breaker components, and enclosures where thin walls and good dielectric properties are needed.
Consumer Appliance Parts: Suitable for intricate components in power tools, kitchen appliances, and personal care devices.
Benefits for Your Business: Faster cycle times increase production capacity and reduce energy consumption per part. Improved flow reduces scrap rates and ensures consistent part quality. The material's robustness can potentially allow for wall thickness reduction, leading to material savings and lighter final products.
Processing Guidelines:
For optimal results with the 70G13HS1L grade, we recommend the following general guidelines. Always refer to the specific material data sheet for detailed instructions.
Drying: Essential. Dry at 80-90°C for 3-4 hours in a dehumidifying hopper dryer to achieve a moisture content below 0.1%.
Melt Temperature: 280 - 300°C.
Mold Temperature: 80 - 100°C. Higher mold temperatures can enhance surface finish and may be beneficial for very thin walls.
Injection Speed: Use moderate to high injection speeds to take full advantage of the material's excellent flow.
Frequently Asked Questions (FAQ):
Q: What exactly does "high-speed crystallization" mean for my molding process?
A: It means this Nylon 66 grade solidifies (crystallizes) much faster in the mold cavity after injection. This allows you to eject the part sooner, significantly reducing the overall cycle time and boosting your production output.Q: Is this material suitable for parts with wall thickness below 1.0mm?
A: Yes, that is its primary design purpose. Its excellent flow properties are specifically tailored for filling thin and complex geometries where standard resins might struggle.Q: Do I need special injection molding machine settings for this grade?
A: While it processes similarly to other PA66 resins, optimal results are achieved by adjusting for its fast crystallization. This typically involves a slightly higher mold temperature and fine-tuning of holding pressure and time. Our technical team can provide specific startup recommendations.Q: How does the moisture sensitivity of this grade compare to standard Nylon 66?
A: Like all polyamides, it is hygroscopic and requires thorough drying before processing. Its moisture absorption rate is similar to standard PA66. Proper drying is non-negotiable to achieve the best mechanical properties and surface appearance.Q: Can this resin be colored or compounded with additives?
A: Absolutely. It is available in natural color for custom coloring. We can also discuss options for adding color masterbatches or specific additives like flame retardants or anti-UV stabilizers to meet your application requirements.Q: What are the main differences between this 70G13HS1L and other "fast-cycle" Nylon grades?
A: This grade is part of DuPont's specialized portfolio, often balancing fast crystallization with a strong set of mechanical properties (stiffness, strength) and thermal resistance. Other fast-cycle grades might sacrifice some properties for even faster cycles; this grade aims for an optimal balance suitable for technical thin-wall applications.Q: What packaging and lead time can I expect?
A: Material is typically supplied in 25kg sealed bags on pallets. Lead times are competitive, and we ship globally from major ports like Shanghai and Ningbo, serving markets across North America, Europe, Asia, and beyond.Q: Does Shanghai Wenqin Plastics provide technical support?
A: Yes. As your supplier, we offer support ranging from material selection and processing advice to troubleshooting. Our operations are backed by a commitment to quality management systems.
