· High rigidity + low deformation: Glass fiber forms a skeleton, significantly reducing thermal expansion and contraction, making it suitable for precision structural parts;
· Enhanced Heat Resistance: Heat resistance is increased by nearly 80°C compared to pure PA6, making it suitable for components operating in high-temperature environments;
· Stable Molding: Modified coupling process results in minimal fiber floating and easy injection molding, enabling high-volume mass production;
· Optional Modifications: Heat-resistant, impact-modified and cold-resistant, UL94-V0 flame-retardant, and low-warpage specialty grades.
Physical Properties
Density: 1.33–1.35 g/cm³; melting point approximately 220°C; molding shrinkage 0.7%–1.1% (significantly lower than pure PA6, ensuring superior dimensional accuracy); moisture absorption at room temperature 2.5%–3%.
Mechanical Properties
Tensile strength: 110–150 MPa; flexural strength: 160–210 MPa; flexural modulus: 6,500–7,500 MPa; notched impact strength (simply supported beam at room temperature): 6–9 kJ/m²; rigidity and creep resistance are far superior to those of unreinforced pure PA6.
Heat Resistance
Heat deflection temperature at 0.45 MPa: 205–215 °C; continuous service temperature: 85–110 °C; short-term peak temperature resistance: 200 °C; resistant to deformation and warping at high temperatures.
Electrical & Chemical Resistance
Excellent insulation properties, with a volume resistivity >10¹⁵ Ω·cm; resistant to engine oil, gasoline, weak acids, and greases, but not resistant to concentrated strong acids; excellent wear resistance and self-lubrication.
Molding Process: Injection molding is preferred; barrel temperature: 240–270°C; mold temperature: 70–90°C. It is recommended to dry the raw material at 80–100°C for 4–6 hours to remove moisture and prevent bubbles and silver streaks in the finished product.
