1. Automotive Industry (Core Applications)
Engine hood panels, intake manifolds, radiator water chambers, water pump housings, throttle body components, chassis brackets, rearview mirror frames, windshield wiper mounts, and small transmission gears (oil-resistant, high-temperature-resistant, and hydrolysis-resistant).
2. Electronics and Electrical Equipment
High-voltage connector bases, circuit breaker bases, relay housings, power coil frames, internal structural components of charging stations, high-power switch housings; V0-rated flame-retardant grades are used for power distribution insulation components.
3. Power Tools & General Machinery
Handheld drill/angle grinder housings, internal gears for impact drills, hydraulic pump bodies, bearing housings, sprockets, small-to-medium-sized drive gears, and load-bearing housings for instruments and meters.
4. Other Industries
Load-bearing brackets for high-end fitness equipment, bicycle pedals, pressure-bearing hardware for bathroom fixtures, gears for office equipment, and small structural brackets for drones.
· Optimal balance of performance and cost: Strength far exceeds GF20, while the price is lower than high-glass-fiber-content materials such as GF35/40, making it the top choice for mass-producing high-strength components;
· Low shrinkage and high precision: A 30% glass-fiber reinforcement structure suppresses thermal expansion and contraction, enabling controlled assembly tolerances for precision snap-fit and multi-cavity components;
· Comprehensive range of modified grades: Available in three major custom grades—hydrolysis-resistant (suitable for automotive cooling systems), V0 flame-retardant (high-voltage electrical applications), and -35°C low-temperature impact-modified;
· Wide molding compatibility: Flow properties superior to high-glass-fiber grades, ensuring smooth mold filling for complex structures and thin-walled large parts, resulting in high first-pass yield.
· Physical Properties: Density: 1.34–1.36 g/cm³; Melting Point: 259–263°C; Molding shrinkage: 0.2%–0.3% in the longitudinal direction and 0.5%–0.7% in the transverse direction; dimensional stability is far superior to that of PA66GF20; 24-hour water absorption: 0.5%–0.7%; minimal deformation due to moisture absorption.
· Mechanical Properties: Tensile strength: 175–190 MPa; flexural strength: 270–290 MPa; flexural modulus: 9,500–10,500 MPa; notched impact strength (simply supported beam): 9–12 kJ/m²; rigidity is significantly higher than that of GF20, with moderate toughness, making it resistant to deformation and cracking under heavy loads.
· Heat Resistance: Heat deflection temperature at 1.8 MPa: 238–248 °C; heat deflection temperature at 0.45 MPa: 258–265 °C; continuous long-term operating temperature: 115–130 °C; short-term peak temperature resistance: 260 °C; suitable for long-term operation in engine compartments and high-temperature electrical enclosures.
· Chemical & Electrical Resistance: Resistant to engine oil, fuel, coolant, and weak acids and alkalis; not resistant to concentrated strong acids; excellent insulation and resistance to tracking; all grades comply with RoHS and REACH environmental standards; features inherent self-lubricating and wear-resistant properties.
· Drying: Dehumidifying drying at 95–110°C for 4–6 hours, with a moisture content of <0.12%, to prevent silver streaks and bubbles;
· Barrel temperature: 265–290°C; nozzle temperature: 270–280°C;
· Mold temperature: 85–100°C, to reduce fiber protrusion and improve product surface finish and dimensional accuracy.
