As a premier supplier of engineering thermoplastics, Shanghai Yunshan Plasticizing Co., Ltd., strategically located in Shanghai, China, is proud to offer the high-performance Celanese PA66 70G33HSL NC010. This 33% glass fiber reinforced grade is engineered for applications demanding exceptional mechanical strength and thermal resistance. Our commitment to reliable sourcing and comprehensive logistics ensures that you receive genuine material with consistent quality, empowering your manufacturing processes to achieve new levels of durability and efficiency.
The Celanese 70G33HSL NC010 is a heat-stabilized, lubricated polyamide 66 resin, specifically formulated to deliver outstanding performance in demanding environments. The incorporation of 33% glass fiber significantly elevates its stiffness, tensile strength, and creep resistance compared to unreinforced PA66. This makes it an ideal candidate for metal replacement projects, offering weight reduction without compromising structural integrity. Its natural color (NC010) provides versatility for custom coloring or use in its raw state.
Key Product Characteristics:
Superior Mechanical Strength: The 33% glass fiber reinforcement provides a dramatic increase in tensile strength and modulus, ensuring parts can withstand high static and dynamic loads.
Excellent Thermal Stability: The 'HSL' designation indicates heat stabilization, allowing components to retain their mechanical properties at elevated temperatures, with a Heat Deflection Temperature (HDT) around 250°C.
Enhanced Dimensional Stability: Glass fibers reduce the material's tendency to shrink and warp, resulting in parts with tight tolerances and excellent dimensional accuracy.
Good Chemical Resistance: Exhibits robust resistance to a wide range of chemicals, greases, and oils, making it suitable for automotive under-the-hood and industrial applications.
Improved Creep Resistance: The glass reinforcement significantly reduces the material's tendency to deform permanently under long-term, continuous stress.
Lubricated for Processing: An internal lubricant is incorporated to improve mold release and flow during injection molding, reducing cycle times and enhancing surface finish.
Natural Color Versatility: Supplied in a natural (NC010) color, it can be easily pigmented during processing or used as-is for non-aesthetic components.
Typical Applications:
The robust property profile of PA66 70G33HSL makes it a preferred material across various demanding industries. Its ability to replace metal parts leads to lighter, more cost-effective assemblies. Common applications include:
Automotive: Engine covers, air intake manifolds, radiator end tanks, cooling fans, structural brackets, and mirror housings.
Electrical and Electronics: Connectors, circuit breakers, coil forms, and insulating components requiring high rigidity and heat resistance.
Industrial Machinery: Gears, cams, bearings, pump housings, and conveyor system components exposed to high wear and mechanical stress.
Consumer Goods: Power tool housings, appliance components, and sporting goods frames where impact resistance and durability are critical.
Technical Specifications Overview:
| Property | Typical Value | Test Standard |
| Density | 1.39 g/cm³ | ISO 1183 |
| Tensile Modulus | 10,500 MPa | ISO 527-2/1A |
| Tensile Stress at Break | 190 MPa | ISO 527-2/1A |
| Flexural Modulus | 9,000 MPa | ISO 178 |
| Charpy Impact Strength (Unnotched, 23°C) | 85 kJ/m² | ISO 179/1eU |
| HDT (1.8 MPa, Unannealed) | 250 °C | ISO 75-2/A |
| Melting Temperature (DSC) | 260 °C | ISO 11357-3 |
Note: These values are typical for the base resin and should not be considered as strict specifications. Actual values can be influenced by processing parameters and part design.
Processing Guidelines:
To achieve the best results with Celanese 70G33HSL, proper handling and processing are essential. The material is supplied in a moisture-resistant package, but pre-drying is recommended to prevent hydrolytic degradation.
Pre-drying: 4-6 hours at 80°C in a dehumidified air dryer is recommended to achieve a moisture content below 0.15%.
Melt Temperature: 280-300°C. The specific temperature should be optimized based on the part geometry and mold design.
Mold Temperature: 80-100°C. A higher mold temperature promotes better surface finish and higher crystallinity, which improves mechanical properties.
Injection Speed and Pressure: Medium to high injection speeds are typically used. Holding pressure should be sufficient to compensate for shrinkage and prevent sink marks.

Frequently Asked Questions (FAQ):
Q1: What is the primary advantage of the 33% glass fiber in Celanese 70G33HSL?
The 33% glass fiber reinforcement dramatically increases the material's tensile strength, stiffness, and heat deflection temperature compared to standard, unreinforced PA66. This makes it suitable for structural applications that must withstand high mechanical loads and temperatures, often serving as a lightweight alternative to metal.
Q2: What does the 'HSL' in the grade name stand for?
'HSL' stands for Heat Stabilized and Lubricated. The heat stabilization package protects the polymer from thermal degradation during processing and in high-temperature end-use environments. The internal lubricant improves the flow of the molten plastic during injection molding, facilitating easier mold filling and part ejection.
Q3: Is this material suitable for outdoor applications with direct UV exposure?
While PA66 70G33HSL has excellent mechanical and thermal properties, it is supplied in a natural color and does not contain a specific UV stabilization package. For long-term outdoor exposure, a black or custom-colored version with UV additives is typically recommended. Please inquire about alternative grades for such applications.
Q4: What is the recommended pre-drying procedure before processing?
To prevent brittleness and achieve optimal surface finish, the material must be properly dried. We recommend drying for 4-6 hours at 80°C (176°F) using a dehumidified air dryer. The target moisture content should be below 0.15%. Even in its original sealed packaging, moisture absorption can occur over time.
Q5: Can you provide a Certificate of Analysis (COA) with the shipment?
Yes, absolutely. As a professional supplier, Shanghai Yunshan Plasticizing Co., Ltd. provides a Certificate of Analysis (COA) and a Material Safety Data Sheet (MSDS) with every shipment. This documentation ensures full traceability and confirms that the product meets the manufacturer's specifications.
Q6: What is the typical packaging for this product?
The standard packaging is a 25 kg moisture-resistant bag, which is then palletized and stretch-wrapped for stability during transport. A full pallet typically contains 1000 kg (40 bags). Custom packaging options may be available for large-volume orders upon request.
Q7: How does this grade compare to a 30% glass-filled PA66?
The 33% glass fiber loading provides a higher level of reinforcement than a standard 30% grade. This translates to slightly higher tensile strength, modulus, and heat deflection temperature. The 70G33HSL is chosen when a design requires that extra margin of mechanical performance and thermal resistance.
Q8: Do you offer sampling for testing and validation purposes?
Yes, we understand the importance of material validation. We can provide small quantities of Celanese 70G33HSL NC010 for your initial testing and color matching. Please contact our sales team with your specific requirements, and we will be happy to arrange a sample shipment.
