As a specialized manufacturer of high-performance engineering plastics, Shanghai Wenqin Plastics Co., Ltd. is proud to introduce our PA66 A3X2G5 Heat-Stabilized Compound. Engineered specifically for demanding applications, this advanced material is the solution for components that must withstand prolonged exposure to elevated temperatures while maintaining critical structural integrity. Our expertise, backed by a commitment to quality systems like ISO 9001, ensures that every batch delivers consistent performance, helping your products achieve greater reliability and longevity in challenging environments.
This compound is not just another nylon; it's a precisely formulated material designed to solve the common failure points in high-temperature mechanical assemblies. By choosing our PA66 A3X2G5, you gain access to a material that combats thermal degradation, preserves mechanical properties under heat, and ultimately reduces warranty claims and maintenance costs for your end products.
Core Product Features & Technical Advantages:
Superior Heat Aging Resistance: The integrated heat stabilization package significantly slows down the degradation process caused by prolonged heat exposure. This means parts retain their strength, stiffness, and dimensional stability far longer than standard PA66 grades, even in continuous high-temperature service.
Enhanced Mechanical Performance: The "A3X2G5" designation indicates a specific formulation with glass fiber reinforcement. This provides an excellent balance of high tensile strength, rigidity, and impact resistance, making it ideal for load-bearing components.
Dimensional Stability & Low Warpage: The compound is engineered for minimal moisture absorption and low thermal expansion, ensuring tight tolerances and reliable fit in assembled parts, which is crucial for mechanical and automotive applications.
Excellent Processability: Designed for efficient injection molding, it offers good flow characteristics and fast cycle times, contributing to higher productivity and lower manufacturing costs for our clients.
Broad Chemical Resistance: Like standard PA66, it maintains good resistance to many oils, fuels, and chemicals, protecting components in harsh under-hood or industrial environments.
Typical Technical Specifications:
| Property | Test Method | Typical Value | Unit |
| Tensile Strength | ISO 527 | 180 - 210 | MPa |
| Flexural Modulus | ISO 178 | 8500 - 10500 | MPa |
| Izod Impact, Notched | ISO 180 | 12 - 18 | kJ/m² |
| HDT @ 1.8 MPa | ISO 75 | > 240 | °C |
| Melting Temperature | ISO 11357 | 260 - 265 | °C |
| Density | ISO 1183 | 1.38 - 1.42 | g/cm³ |
Benefits to Your Business:
Extended Product Life: Components last longer in high-heat conditions, reducing replacement frequency and improving your product's reputation for durability.
Design Freedom: Enables the design of complex, thin-walled parts that must perform under thermal stress, potentially replacing metals for weight savings.
Reliable Supply: Sourced from our dedicated facility, we provide consistent material quality and reliable logistics through major ports like Shanghai and Ningbo.
Cost-Effective Performance: Achieves the high-temperature performance of more expensive specialty polymers at a more competitive price point for PA66-based compounds.
Frequently Asked Questions (FAQ):
Q: What does "A3X2G5" mean in the grade name?
A: This is a common industry designation for PA66 compounds. "A3" typically refers to the base PA66 resin type, "X2" often indicates a specific heat stabilization package, and "G5" usually denotes a 25% or 30% glass fiber content (exact percentage available upon request). It signifies a balanced, heat-stabilized, glass-reinforced grade.Q: How does heat stabilization improve the performance compared to standard PA66?
A: Standard PA66 can undergo oxidation and molecular chain scission when exposed to air at high temperatures for long periods, leading to embrittlement and loss of mechanical properties. The heat stabilizers in this compound act as antioxidants, significantly slowing this process and helping the material retain its strength and toughness over time.Q: What is the maximum continuous use temperature for this compound?
A> While the Heat Deflection Temperature (HDT) is over 240°C, the maximum continuous use temperature in air typically ranges from 120°C to 150°C, depending on the specific application, load, and required service life. Detailed guidance can be provided based on your part design.Q: Is this material suitable for parts in contact with fuels or oils?
A: Yes, PA66 generally has good resistance to many hydrocarbons, including fuels and lubricating oils. However, for specific fluid compatibility, it is recommended to conduct tests or consult our technical data for the exact chemical resistance profile.Q: Do you provide technical data sheets and processing guidelines?
A: Absolutely. Comprehensive technical data sheets (TDS) with full property lists and recommended injection molding parameters (temperature profiles, drying conditions, etc.) are available upon request to ensure optimal processing.Q: Can this compound be colored?
A: Yes. While the natural color is off-white/beige, we can supply custom-colored compounds. Masterbatch coloring is a common and effective method. Color matching services are available for specific requirements.Q: What are the typical applications for this PA66 grade?
A: It is ideally suited for under-hood automotive components (e.g., engine covers, air intake manifolds, radiator end tanks), electrical connectors in high-temperature zones, industrial pump housings, gears, and bearings operating in heated environments.Q: What is your minimum order quantity (MOQ) and lead time?
A: Our MOQ is flexible to accommodate both trial projects and large-scale production. Standard lead times are competitive, and we can discuss expedited options. Please contact us with your specific quantity and timeline needs.
