Reinforced PA66 for Elevated-Temperature Applications
Heat Resistant Reinforced Nylon Compound is based on reinforced PA66 and is developed for components that need to maintain structural stability under elevated temperatures and mechanical loads.
The material combines high strength, good heat resistance, and dimensional stability. Typical applications include automotive exhaust pipe brackets and plastic fuel tank bottom housings. It can also be considered for plastic fuel tank components, air-conditioning outlets, and other injection-molded parts where thermal deformation and assembly accuracy are important.
For components positioned near heat sources or required to maintain their shape during extended use, reinforced PA66 provides a mechanical and thermal performance combination that can be matched to the actual operating conditions.
Heat Resistance Supported by Mechanical Strength
The typical reinforced grades have a density of 1.35–1.36 g/cm³. Tensile strength at break ranges from 130 to 190 MPa, while flexural strength ranges from 162 to 220 MPa.
Flexural modulus is 6400–8900 MPa, giving molded structures the rigidity needed to resist deformation under load. Notched Izod impact strength is 14–16 kJ/m².
Under a load of 1.82 MPa, the heat deflection temperature is 190–215°C. The molding shrinkage range is 0.25%–0.50%.
These parameters make Heat Resistant Reinforced Nylon Compound suitable for purchasing projects where dimensional stability must be evaluated together with mechanical strength and exposure to elevated temperatures.
Key Information to Confirm Before Material Selection
Heat-resistant reinforced PA66 is especially relevant when high-temperature rigidity and dimensional stability are more important than simply achieving high room-temperature strength.
For an automotive exhaust pipe bracket, buyers should consider temperature changes, continuous mechanical load, and the need to maintain structural shape. Plastic fuel tank bottom housings and related components require attention to load-bearing performance, heat resistance, and assembly dimensions.
When discussing a material grade, it is useful to provide the expected long-term operating temperature, short-term temperature changes, load direction, installation space, and target dimensional tolerance.
For complex or appearance-sensitive parts, mold runners, gate positions, and wall thickness can also influence molding results. Sample trials can therefore help determine whether the selected grade is suitable for the actual part and existing injection process.
Technical Coordination for Sampling and Production
Changshu Diyou New Material Technology Co., Ltd. has long-term technical experience in polymer modification. Its production base includes raw material handling, extrusion modification, injection molding verification, and material performance testing.
For heat-resistant reinforced nylon, the technical team can support formulation selection, extrusion process adjustment, and performance verification according to the required application.
Production and inspection processes are managed under an ISO 9001 quality management system. During batch purchasing, communication can focus on heat deflection temperature, tensile strength, flexural modulus, molding shrinkage, and actual working conditions.
For customers evaluating Heat Resistant Reinforced Nylon Compound in an existing product, technical support can also cover mold trials, injection parameter adjustment, and analysis of material-related issues found during subsequent application.
