GX400-35K Carbon Fiber Tow — Wet-Spun | JiLin Tangu

GX400-35K wet-spun PAN-based carbon fiber tow — general-purpose wet-spun grade

Tensile strength 4,200–4,500 MPa · Modulus ≥235 GPa

Low density 1.77±0.03 g/cm³ · soft handle & excellent resin wettability

For prepreg, vacuum infusion (VARTM), and composite reinforcement

Carbon fiber is a continuous filament with excellent mechanical properties, low density, heat and corrosion resistance, fatigue resistance, a small thermal expansion coefficient, and good electrical and thermal conductivity — properties that translate directly into lighter, stronger, and more durable composite parts.

GX500-35K Carbon Fiber Tow — High-Strength Wet-Spun | JiLin Tangu

GX500-35K wet-spun PAN-based carbon fiber tow — high-strength wet-spun grade

Tensile strength 4,500–4,900 MPa · Modulus ≥235 GPa

Low density 1.77±0.03 g/cm³ · soft handle & excellent resin wettability

For prepreg, vacuum infusion (VARTM), and composite reinforcement

As a continuous PAN-based reinforcement, GX500 carbon fiber offers low density, outstanding heat and corrosion resistance, superior fatigue endurance, minimal thermal expansion, and excellent electrical/thermal conductivity — combined here with a higher tensile strength grade for demanding structural applications.
