As a specialized plastics supplier based in Shanghai, China, Shanghai Yunshan Plasticizing Co., Ltd. is proud to offer genuine BASF Ultramid A3UG5 – a premium 30% glass fiber reinforced Polyamide 66 (PA66) engineered specifically for demanding automotive applications. This high-performance nylon compound delivers exceptional mechanical strength, rigidity, and thermal stability, making it an ideal solution for manufacturers seeking reliable materials for critical under-the-hood and structural components. Our strategic location in Shanghai ensures efficient logistics and reliable supply chains for both domestic and international clients.
Engineered by BASF, a global leader in polymer technology, Ultramid A3UG5 stands out in the competitive automotive materials market. Its formulation provides a superior balance of properties essential for modern vehicles:
- Enhanced Mechanical Performance: The 30% glass fiber reinforcement significantly boosts tensile strength, flexural modulus, and impact resistance compared to standard PA66, even at elevated temperatures.
- Superior Heat Resistance: Maintains structural integrity and dimensional stability at continuous use temperatures typically encountered in engine compartments (up to approx. 200°C/392°F short-term).
- Excellent Chemical Resistance: Withstands exposure to automotive fluids like oils, greases, coolants, and fuels, ensuring long-term component reliability.
- Low Creep & High Fatigue Endurance: Performs reliably under constant stress and cyclic loading conditions, crucial for parts like clips, brackets, and housings.
- Good Electrical Insulation Properties: Suitable for electrical connectors and sensor housings.
- Predictable Processing: Optimized for injection molding, offering good flow characteristics and consistent mold filling.

Frequently Asked Questions (FAQ):
Q1: Is Ultramid A3UG5 suitable for parts exposed to engine oil and coolant?
A1: Yes, PA66 GF30, like Ultramid A3UG5, is known for its good resistance to a wide range of automotive fluids, including engine oils, transmission fluids, brake fluids, and coolants. Long-term exposure testing under typical operating conditions is recommended for specific applications.
Q2: How does the heat deflection temperature (HDT) of A3UG5 compare to standard PA66?
A2: The 30% glass fiber reinforcement significantly increases the HDT. While unfilled PA66 might have an HDT (1.8 MPa) around 70-90°C, Ultramid A3UG5 offers an HDT of approximately 250°C, making it suitable for under-hood applications.
Q3: Can this material be used for snap-fit connectors?
A3: Yes, its combination of stiffness and reasonable impact strength makes it suitable for snap-fit designs. Careful design considering the fiber orientation is crucial for optimal performance.
Q4: Does Shanghai Yunshan provide material certificates?
A4: Yes, we supply full material documentation, including Certificates of Analysis (CoA) and Safety Data Sheets (SDS), ensuring traceability back to BASF.
Q5: What are the typical drying conditions required before processing?
A5: PA66 is hygroscopic and must be thoroughly dried before processing. Typical recommendations are drying at 80-90°C (176-194°F) for 4-6 hours in a desiccant dryer to achieve a moisture content below 0.2%.
Q6: What is the minimum order quantity (MOQ) for Ultramid A3UG5?
A6: MOQ can vary depending on packaging and current stock levels. Please contact our Shanghai sales team directly for specific MOQ information tailored to your needs. We strive to be flexible.
Q7: Is this grade available in colors other than natural?
A7: The standard supply is natural (off-white). Custom coloring is often possible through compounding. Please inquire about specific color requirements.
Q8: How does A3UG5 perform in terms of warpage during molding?
A8: While glass fiber reduces shrinkage compared to unfilled PA66, anisotropic shrinkage can still occur due to fiber orientation, potentially leading to warpage. Careful mold design (gate location, cooling) and optimized processing parameters are essential to minimize this.
