PA66 GF35 Applications
Automotive covers and under-hood housings.
Cylinder-head covers and other housings need stiffness around fasteners, ribs and sealing surfaces. Match the grade to the temperature cycle and the fluids that contact the part.
Cooling-fan shrouds, blades and frames.
These parts need dimensional control around rotating assemblies and mounting points. Check balance, vibration and weld-line performance on molded samples.
Pump impellers, machinery housings and mounting brackets.
Use the drawing to define bearing seats, bolt loads and critical tolerances. Moisture, fiber orientation and sustained load affect the final fit and performance.
Processing and Part Checks
Use the selected grade’s drying and molding instructions. Check gate position, fiber orientation, weld lines, shrinkage and critical dimensions during trials. Confirm performance on parts made with the intended tool and process.
For finished components, continue to ép phun. For a material comparison, use the engineering plastics range.
Material Supply and Manufacturing Support
Nhựa nylon connects engineering plastic supply with custom manufacturing. WANHAN is our cooperating compounding factory; the photographs below show its material-feeding equipment, extrusion process and laboratory.
Grade and formulation selection
Share your current grade, application and operating conditions. We coordinate the material review and identify the matching datasheet for the formulation offered.
Quality documents for your order
Specify the TDS, batch records, inspection requirements or compliance files your purchasing team needs. The documents and acceptance criteria are agreed for the quoted material.
Support beyond resin pellets
For a finished component, connect material selection with part design, tooling and molding review. Start with the drawing, expected quantity and critical dimensions.
Cooperating Factory Management-System Certificates
The supplied ISO 9001, ISO 14001 and ISO 45001 certificates identify Guangdong Wanhan as the certified entity. Their scope concerns modified plastic granules and the related management activities; it does not certify every material grade or every finished-part manufacturing service.
Review manufacturing capabilities and quality documentation. For document approval, match the legal entity, certificate scope and quoted grade.
PA66 GF35 — Frequently Asked Questions
What does PA66 GF35 mean?
It is nylon 66 reinforced with 35% glass fiber. The product is supplied as pellets; PA66 WHG35A is the supplier reference grade for the typical properties shown here.
Which applications are suitable candidates for PA66 GF35?
Candidates include under-hood housings, engine covers, fan shrouds, pump impellers, motor frames and mounting brackets. Suitability depends on the part geometry, load, temperature and fluid exposure.
Does the listed HDT mean the part can run continuously at that temperature?
No. Heat deflection temperature is a test result under the stated method and loading. It is not a continuous service-temperature limit. Share the operating temperature, duration and load for material review.
How should I allow for moisture and fiber orientation?
Use the quoted grade’s drying instructions and agree the relevant conditioning state. Gate position and fiber direction can affect shrinkage and dimensions, so validate critical fits on molded samples.
Can PA66 GF35 be used around automotive fluids?
A pump or under-hood application still needs a compatibility review for the actual fluid, concentration, temperature and exposure time. The application image alone does not establish chemical compatibility or automotive approval.
Which documents and details should I request for a quote?
Ask for the current PA66 WHG35A TDS, or the TDS for the exact alternative being offered. Send application conditions, color, quantity, destination and any required inspection or compliance documents; include a drawing for finished parts.
Request Material Data and a Quote
Send the application, current material if available, service temperature, load or fluid exposure, color, expected quantity and delivery destination. Add a drawing when finished parts are needed.
