Shanghai Wenqin Plastics Co., Ltd., established in 2020, specializes in providing high-performance engineering plastics for demanding industrial applications. As a dedicated supplier, we understand the critical role material selection plays in the longevity and efficiency of mechanical systems. Our offering of DuPont PA66 73G40T, a 40% glass fiber reinforced nylon 66 compound, is specifically engineered to meet the rigorous requirements of industrial gear manufacturing. This material delivers a superior balance of mechanical strength, dimensional stability, and wear resistance, directly contributing to reduced downtime and enhanced performance in your gear-driven equipment.
The core value of this product lies in its ability to replace traditional metal gears in many scenarios, offering benefits such as weight reduction, noise dampening, and corrosion resistance. By sourcing this grade from Shanghai Wenqin Plastics, you gain access to a reliable material backed by our commitment to quality and customer support, supported by a portfolio of management system certifications including ISO9001 and ISO14000.
Detailed Product Characteristics & Advantages:
- Enhanced Mechanical Performance: The 40% glass fiber loading significantly increases tensile strength, flexural modulus, and impact resistance compared to unfilled PA66. This results in gears that can withstand higher loads and more severe operating conditions.
- Excellent Thermal Stability: Glass reinforcement improves the heat deflection temperature, allowing gears to perform reliably in environments with elevated temperatures.
- Superior Wear and Abrasion Resistance: The composite structure minimizes wear on gear teeth, leading to longer service life and reduced maintenance intervals.
- Low Creep and High Dimensional Accuracy: The material exhibits minimal deformation under sustained load (creep), ensuring precise gear geometry and consistent meshing over time.
- Good Chemical Resistance: PA66 base offers resistance to many oils, greases, and mild chemicals commonly found in industrial settings.
- Design Flexibility for Molding: Suitable for injection molding, it allows for the production of complex gear geometries, integrated features, and cost-effective mass production.

Benefits for Your Business:
- Extended Gear Lifecycle: Reduced wear translates to fewer replacements and lower long-term costs.
- Improved System Efficiency: Lightweight gears can reduce inertial loads, potentially improving energy efficiency.
- Reduced Noise Operation: Plastic gears often operate more quietly than metal counterparts.
- Corrosion-Free Performance: Unlike some metals, this material does not rust, ideal for humid or wash-down environments.
- Cost-Effective Production: Injection molding of plastic gears can be more economical than machining metal gears, especially for complex shapes.

Frequently Asked Questions (FAQ):
-
Q: What is the main difference between PA66 73G40T and standard unfilled nylon?
A: The key difference is the addition of 40% glass fibers. This dramatically improves stiffness (flexural modulus), tensile strength, and heat resistance, making it suitable for high-load, precision applications like gears, whereas unfilled nylon is more flexible and suited for lower-stress parts. -
Q: Can this material be used for gears in high-temperature environments?
A: Yes, the glass fiber reinforcement raises the heat deflection temperature (HDT), allowing it to perform under higher thermal conditions than unfilled PA66. However, the exact maximum continuous use temperature should be verified based on your specific load and environment. -
Q: Is color customization available?
A: The natural color of the compound is typically off-white. Custom colors can often be achieved by adding masterbatch during molding, subject to specific requirements and feasibility checks. -
Q: What are the typical processing considerations for molding gears with this material?
A> Due to the high filler content, it requires robust injection molding equipment. Mold design should account for low shrinkage. Proper drying before processing is crucial to prevent moisture-related defects. Processing parameters like temperature and pressure may need adjustment compared to unfilled grades. -
Q: How does the wear resistance compare to metal gears?
A> While not matching the wear resistance of hardened steels, PA66 73G40T offers excellent wear resistance for many applications, especially when lubrication is used. Its advantage includes weight savings, noise reduction, and corrosion resistance where metal would fail. -
Q: What packaging and shipment options do you offer?
A> Material is typically supplied in standard sealed plastic bags to prevent moisture contamination. Shipment is arranged from Shanghai or Ningbo ports. Packaging and logistics details can be customized based on order volume and destination. -
Q: Do you provide technical data sheets and application support?
A> Yes, detailed technical data sheets with property values are available upon request. Our team can offer general guidance on material selection and processing for gear applications. -
Q: Are there any industry standards or certifications specific to this plastic grade?
A> The grade itself (73G40T) is a DuPont specification. Our company holds various management system certifications (e.g., ISO9001) ensuring our supply processes are controlled and reliable.
