As a specialized manufacturer in advanced engineering plastics, Shanghai Yunshan Plasticizing Co., Ltd. is dedicated to providing high-performance material solutions for demanding automotive applications. Our PA66 G3300HSL NC010 is specifically engineered to meet the rigorous challenges of underhood environments, offering exceptional long-term heat aging resistance and reliable mechanical performance. This material represents our commitment to supporting the automotive industry's evolution towards more efficient and durable vehicles.
This high-temperature stabilized grade is formulated to withstand the continuous thermal stress encountered near engines, transmissions, and other powertrain components. By choosing our PA66 G3300HSL NC010, you gain access to a material that helps extend component lifespan, reduce warranty claims, and contribute to overall vehicle reliability, making it a strategic choice for Tier 1 suppliers and OEMs focused on quality and performance.
Core Features and Technical Advantages:
Superior Heat Aging Performance: The G3300HSL formulation is designed to retain a high percentage of its key mechanical properties, such as tensile strength and impact resistance, even after prolonged exposure to elevated temperatures typical in underhood applications (e.g., 130°C to 150°C continuous use). This ensures components do not become brittle or fail prematurely.
Enhanced Dimensional Stability: The combination of PA66 resin and glass fiber reinforcement provides low coefficient of thermal expansion and excellent resistance to creep under load at high temperatures. This is critical for components like connectors, housings, and brackets that must maintain precise tolerances and fit.
Balanced Mechanical Properties: Offers a robust profile of stiffness, strength, and toughness. The glass fiber reinforcement significantly improves tensile and flexural modulus compared to unfilled PA66, allowing for part design that is both strong and lightweight.
Non-Halogenated Flame Retardancy (NC010): This grade meets specific flame retardancy requirements without the use of halogenated additives, aligning with environmental regulations and material sustainability goals within the automotive sector. It helps components meet necessary industry standards for safety.
Excellent Processability: Formulated for consistent flow and molding behavior in injection molding processes. This can lead to reduced cycle times, lower reject rates, and improved surface finish on final parts, enhancing overall manufacturing efficiency.
Chemical and Fluid Resistance: Inherently resistant to a wide range of automotive fluids, including oils, greases, coolants, and weak alkalis, protecting components from degradation and ensuring long-term functional integrity.
Typical Technical Specifications:
| Property | Test Method | Typical Value | Unit |
|---|---|---|---|
| Density | ISO 1183 | 1.52 | g/cm³ |
| Tensile Strength (Yield) | ISO 527 | 180 | MPa |
| Flexural Modulus | ISO 178 | 9500 | MPa |
| Charpy Notched Impact Strength (23°C) | ISO 179/1eA | 12 | kJ/m² |
| Heat Deflection Temperature (1.8 MPa) | ISO 75-1/-2 | 255 | °C |
| Flammability Rating | UL 94 | V-0 (0.8mm) | - |
Benefits for Your Automotive Projects:
Extended Component Service Life: Resistance to thermal aging means parts like sensor housings, engine covers, and electrical connectors last longer, reducing the need for replacements and improving vehicle durability.
Design Freedom and Weight Reduction: The high strength-to-weight ratio allows engineers to design thinner, lighter parts without compromising performance, contributing to overall vehicle fuel efficiency.
Reliability in Harsh Conditions: Components maintain their shape, strength, and electrical insulation properties even when exposed to constant heat, vibration, and fluid contact, ensuring consistent system operation.
Streamlined Compliance: The non-halogenated flame retardant system helps parts meet automotive OEM material specifications and environmental directives more easily.
Cost-Effective Manufacturing: Good flow properties and thermal stability can lead to faster molding cycles and lower energy consumption during processing, optimizing production costs.

Frequently Asked Questions (FAQ)
What is the maximum continuous use temperature for PA66 G3300HSL NC010?
This grade is engineered for long-term exposure in environments typically ranging from 130°C to 150°C. Its heat-stabilized formulation is designed to retain key mechanical properties over extended periods at these temperatures, which is suitable for many underhood applications.Can this material be used for parts in direct contact with engine oil or coolant?
Yes, PA66 inherently offers good resistance to many automotive fluids, including engine oils, transmission fluids, and coolants. The G3300HSL grade maintains this resistance even at elevated temperatures, making it suitable for housings, covers, and connectors in fluid environments.What does "NC010" in the grade name signify?
"NC010" typically indicates a natural color (unpigmented) and a specific non-halogenated flame retardant system. This combination is often specified for applications where color is not critical or will be painted, and where halogen-free materials are required.How does the heat aging performance compare to standard PA66 grades?
The "HSL" designation highlights its High-temperature Stabilized and Long-term heat aging performance. It will retain a significantly higher percentage of its original tensile strength and impact resistance after hundreds or thousands of hours at high temperature compared to a non-stabilized standard PA66 grade.Is this material suitable for metal replacement in underhood applications?
Absolutely. Its combination of high strength, stiffness, heat resistance, and lighter weight makes it an excellent candidate for replacing metals in components like brackets, pulleys, and covers, contributing to weight reduction and part consolidation.What are the typical injection molding processing parameters?
Recommended melt temperatures are usually in the range of 280°C to 300°C, with mold temperatures between 80°C and 100°C. Due to its moisture sensitivity, proper drying before processing (e.g., 4-6 hours at 80°C-90°C) is essential to achieve optimal properties and surface finish.Does Shanghai Yunshan Plasticizing provide technical data sheets and support?
Yes, comprehensive technical data sheets (TDS) with detailed property data and processing guidelines are available upon request. Our technical team can also provide application-specific support and recommendations.Can custom colors or formulations be developed?
Custom color masterbatches can often be added during compounding. For significant formulation changes, such as different reinforcement levels or additive packages, we recommend contacting our development team to discuss feasibility and minimum order quantities.
