Automotive Industry (Primary Applications): Engine hood panels, intake manifolds, radiator end caps, throttle brackets, fuel pump housings, headlight frames, high-voltage connectors for new energy vehicles, and small chassis components (oil- and heat-resistant).
Electronics and Electrical Equipment: Circuit breaker bases, terminal blocks, coil frames, power switch housings, power tool enclosures, and insulated socket components (insulation + heat resistance).
General Machinery: Small transmission gears, pump impellers, bearing housings, sprockets, load-bearing housings for instruments and meters, and wear-resistant transmission components.
Others: High-end outdoor hardware, structural components for fitness equipment, and precision load-bearing fittings for bathroom fixtures.

Ultra-high rigidity and low warpage: 30% glass fiber reinforcement, extremely low shrinkage rate, suitable for high-precision assembly components;
Enhanced heat resistance: Superior high-temperature resistance compared to GF20, suitable for high-temperature engine compartment conditions;
Low fiber protrusion for easy mass production: The optimized coupling modification process minimizes exposed glass fibers on the surface of Glass Fiber Reinforced PA66, ensuring a smoother appearance and stable performance during high-volume injection molding.
Customizable in Multiple Specifications: Cold-resistant (-40°C) toughened grades, UL94-V0 flame-retardant grades, and low-warpage specialty grades are all available upon request.
