Polyamide 46 (PA46), also known as nylon 4-6, is a high-temperature polyamide characterized by excellent heat resistance, mechanical strength, and rapid crystallization. These features make it especially suitable for demanding applications where materials are exposed to high temperatures and mechanical stress.Polyamide 46 (PA46), also known as nylon 4-6, is a high-temperature polyamide characterized by excellent heat resistance, mechanical strength, and rapid crystallization.

• Automotive industry: Production of engine and transmission components such as gears, bearings, thermostat housings, and other parts exposed to high temperatures and mechanical loads.
• Electronics and electrical engineering: Manufacturing of connectors, switches, relays, and other components requiring high thermal resistance and dimensional stability.
• Industrial equipment: Use in gears, bearings, and mechanical parts exposed to wear and high temperatures.
• Kitchen appliances: Components like oven handles and other parts exposed to high heat.
• High heat resistance: PA46 has a melting point of approximately 295 °C, which is higher than other polyamides like PA6 and PA66. This enables its use in high
• temperature environments.
• Excellent mechanical strength and stiffness: Thanks to high crystallinity, the material maintains its strength and rigidity even at elevated temperatures.
• Rapid crystallization: PA46 crystallizes quickly, allowing shorter injection molding cycles and improved processing productivity.
• Good wear and friction resistance: The material has low wear and a low coefficient of friction, making it ideal for moving parts.
• Good chemical resistance: PA46 is resistant to many chemicals, including oils, fuels, and some solvents.
• Higher cost: PA46 is more expensive to produce compared to other polyamides, which may limit its use to applications requiring its unique properties.
• Moisture sensitivity: Like other polyamides, PA46 absorbs moisture, which can affect dimensional stability and mechanical properties.
• Processing complexity: Due to its high melting point and fast crystallization, precise control of processing parameters is necessary.
