As a specialized manufacturer of high-performance engineering plastics, Shanghai Wenqin Plastics Co., Ltd. is dedicated to providing robust material solutions for demanding industrial applications. Our PA66 Granules, specifically the FG172 Glass Fiber Reinforced grade, are engineered to meet the rigorous requirements of components that endure significant mechanical stress, vibration, and harsh operational environments. We combine advanced compounding technology with stringent quality control to deliver a material that offers exceptional reliability, dimensional stability, and longevity, helping our clients build more durable and efficient products.
This grade is formulated to excel where standard plastics fall short. The integration of high-quality glass fibers into the PA66 matrix creates a synergistic effect, significantly enhancing the base polymer's properties. The result is a material that provides an optimal balance between strength, stiffness, and processability, making it a preferred choice for engineers and designers across various sectors.
Superior Mechanical Performance: The primary advantage of our FG172 grade is its dramatically improved tensile strength, flexural modulus, and impact resistance compared to unfilled PA66. This translates directly into the ability to design thinner, lighter parts that do not compromise on performance or safety.
Enhanced Thermal and Dimensional Stability: Glass fiber reinforcement reduces the coefficient of thermal expansion and improves the heat deflection temperature (HDT). Components maintain their shape and dimensional accuracy over a wider temperature range and under load, which is critical for precision assemblies.
Excellent Creep Resistance: Parts made from this material demonstrate remarkable resistance to deformation under long-term static loads, ensuring consistent performance and reliability throughout the product's lifecycle.
Good Chemical Resistance: It retains the favorable chemical resistance of PA66 against many oils, greases, and hydrocarbons, making it suitable for automotive and industrial machinery applications.
The technical specifications below outline the key properties that define this high-performance material. These values are typical and can be verified through our technical datasheets.
| Property | Test Method | Typical Value | Unit |
|---|---|---|---|
| Tensile Strength | ISO 527 | 180 - 210 | MPa |
| Flexural Modulus | ISO 178 | 9000 - 11000 | MPa |
| Izod Impact (Notched) | ISO 180/1A | 10 - 15 | kJ/m² |
| Heat Deflection Temp. (1.8 MPa) | ISO 75-1/-2 | 250 - 255 | °C |
| Density | ISO 1183 | 1.35 - 1.45 | g/cm³ |
For manufacturers, the benefits are clear and tangible. Switching to or specifying our FG172 PA66 granules can lead to: extended product lifespans through reduced wear and failure; opportunities for part consolidation and lightweighting without sacrificing strength; improved performance consistency in batch-to-batch production; and overall cost savings by reducing warranty claims and maintenance needs. It is particularly advantageous in replacing metals or more expensive engineering plastics in many structural applications.
Our commitment to quality is backed by a robust management system, including ISO 9001 certification, ensuring that every batch of material meets the specified performance criteria. Served from our strategic location in Shanghai with major ports like Shanghai and Ningbo, we efficiently support a global clientele across North America, Europe, Asia, and other key markets. Whether you are developing new components or seeking to upgrade existing ones, our technical team is ready to provide support.

Frequently Asked Questions (FAQ)
Q1: What is the typical glass fiber content in the FG172 grade?
A1: The "FG172" designation typically indicates a glass fiber content in the range of 30% to 35% by weight. This level provides an optimal balance between enhanced mechanical properties and good processability during injection molding.
Q2: How does this material perform in humid environments compared to standard PA66?
A2: While PA66 absorbs moisture, which can plasticize it and reduce stiffness, the glass fiber reinforcement in the FG172 grade helps mitigate this effect. The dimensional stability and strength retention in humid conditions are generally superior to unfilled PA66, but proper drying before processing is always recommended.
Q3: Is it suitable for food contact or medical applications?
A3: This standard FG172 grade is formulated for industrial mechanical parts. For applications requiring food contact or medical compliance, specific grades with relevant certifications and stabilizers are available. Please inquire about our specialized product lines for such needs.
Q4: What are the key considerations for injection molding this material?
A4: Critical steps include thorough drying to remove moisture (recommended at 80-90°C for 4-6 hours), use of a screw with a compression ratio suitable for reinforced plastics, and maintaining adequate mold temperatures (80-120°C) to ensure good surface finish and minimize warpage.
Q5: Can you provide material in colors other than natural?
A5: Yes. While natural (off-white) is standard, we can supply pre-colored black granules or masterbatches for on-site coloring. Custom color matching is available upon request, subject to minimum order quantity requirements.
Q6: What is the main difference between PA6 and PA66 GF grades?
A6: PA66 generally offers a higher melting point, better thermal stability, and slightly higher stiffness and strength at elevated temperatures compared to PA6. The FG172 grade based on PA66 is therefore often chosen for applications where higher continuous use temperatures are a factor.
Q7: Do you offer technical support for part and mold design?
A7: We provide basic technical data sheets and processing guidelines. For in-depth part design and mold flow analysis support, we can connect you with our partners or recommend engineering resources familiar with glass-fiber reinforced nylon.
Q8: What is your standard lead time and packaging?
A8: Standard grades are typically available from stock or with a short lead time. They are packaged in 25 kg moisture-proof bags on pallets. For larger volumes, bulk packaging options can be discussed.
