Black Heat Stabilized Nylon PA66 Compounds For Automotive Air Intake Manifold

Heat Stabilized Nylon PA66 Compounds For Automotive Air Intake Manifold Applications

Product Description

Heat Stabilized Nylon PA66 compounds are engineering-grade thermoplastics specifically developed for demanding automotive engine applications such as air intake manifolds, resonator tubes, and engine air ducts. This material is reinforced with heat-resistant stabilizers to ensure consistent mechanical performance when exposed to long-term high temperatures and under-the-hood conditions. Compared to unmodified nylon, this PA66 compound offers superior thermal stability, dimensional control, and resistance to oxidation, making it an ideal solution for components that operate continuously in engine compartments.

The material combines lightweight design, high mechanical strength, and resistance to automotive fluids, enabling manufacturers to replace traditional metals or thermoset plastics while reducing cost and vehicle weight. Typical uses include intake manifolds, turbocharger air ducts, charge air coolers, and resonator housings.

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.

Precautions

• Pre-drying is essential: Dry the granules at 80–100°C for 4–6 hours before processing to avoid hydrolysis and surface defects.

• Mold design: Ensure uniform wall thickness to minimize internal stress and prevent warpage under thermal cycling.

• Processing temperature: Maintain melt temperature at 260–290°C for optimal mechanical strength.

• Usage environment: For turbocharged engines with higher operating temperatures, grades with higher heat stabilizer content are recommended.

Features, Advantages & Properties

• Heat stability: Continuous use at 130–150°C, with excellent resistance to oxidation and hot air aging.

• High mechanical strength: Withstands vibration and mechanical stress from engine operation.

• Lightweight solution: Reduces overall vehicle weight compared to metal intake pipes.

• Excellent dimensional stability: Minimal deformation under thermal cycling.

• Fluid resistance: Resistant to engine oil, coolants, and under-hood chemicals.

• Customizable grades: Available in black or natural; glass fiber reinforcement levels (15%, 30%, 35%) for different mechanical needs.

Working Principle & Applications

The incorporation of heat stabilizers into the nylon matrix significantly slows down the degradation process caused by heat and oxygen exposure. When reinforced with glass fibers, the compound achieves enhanced rigidity and thermal resistance, making it suitable for long-term use in engine compartments.

 Applications include:

• Automotive air intake manifolds – ensuring stable airflow and reducing fuel consumption

• Turbocharger ducts and charge air coolers – resisting high-temperature airflow

• Engine resonator housings – reducing vibration and noise

• Other under-hood components – brackets, connectors, and housings requiring heat stability

By combining durability, thermal resistance, and cost-effectiveness, Heat Stabilized Nylon PA66 compounds provide an optimal solution for automotive OEMs and tier suppliers seeking reliable materials for next-generation engines.
