High Strength Pa66 Glass Fiber Reinforced Polyamide 25Kg/Bag For Automotive Engine Cooling Fans

Product Description

The Glass Fiber Reinforced Nylon PA66 Compounds are specifically engineered for automotive engine cooling fans, delivering an optimal balance of strength, stiffness, and heat resistance. With 30–50% glass fiber reinforcement, this grade offers superior mechanical strength and dimensional stability, enabling the fan blades to withstand high rotational speeds and continuous thermal stress inside the engine compartment.

Unlike unfilled nylon, this material minimizes warpage and provides enhanced fatigue resistance, ensuring long service life even under demanding driving conditions. It is the preferred choice of automotive OEMs and Tier 1 suppliers for engine cooling systems.

Properties Data Sheet

Notes: The general guidelines are only for reference. Exact settings have to follow the product and machine conditions.

Avoid contact with other materials, dust and debris in the injection processing.

Avoid long time stay in the barrel in the injection processing.

Usage Notes

• Drying required: Pre-dry at 100–120°C for 4–6 hours to prevent moisture-induced defects.

• Molding temperature: 270–300°C; mold temperature 80–100°C for best dimensional stability.

• Design considerations: Optimize blade thickness and root design to minimize stress concentration.

• Storage: Keep sealed in moisture-proof packaging; process promptly after drying.

• Color availability: Standard in black, but can be customized in gray or natural for specific OEM requirements.

Features, Advantages & Technical Highlights

• High Mechanical Strength – With 30–50% glass fiber reinforcement, tensile strength reaches 150–220 MPa, supporting stable high-speed rotation.

• Excellent Heat Resistance – Continuous use at 120–150°C, with short-term resistance up to 220°C.

• Outstanding Fatigue Resistance – Maintains structural integrity under long-term vibration and high-frequency cycles.

• Dimensional Stability – Low shrinkage and low warpage ensure precise fan blade geometry.

• Good Impact Resistance – Withstands flying debris or sudden loads without cracking.

• Weight Reduction – Replaces metals, reducing overall fan weight while maintaining strength.

Working Principle: The integration of glass fibers into the PA66 matrix significantly improves modulus and reduces creep. This ensures the cooling fan maintains aerodynamic performance and structural reliability under both thermal and mechanical stresses.
