What is PA12 LCF30 material?
Long Carbon Fiber Reinforced Polyamide 12
LFT-G® PA12 LCF30 is a high-performance injection molding compound with a 30% long carbon fiber-reinforced polyamide 12 matrix. It delivers exceptional mechanical strength, superior fatigue resistance, and outstanding heat deflection up to 179°C. The advanced long-fiber architecture retains fiber length in final parts, enabling lightweight structural components without compromise.
Key Advantages
High Stiffness
Excellent load-bearing capability.
Lightweight
Ideal for metal replacement.
Impact Tough
Superior damage resistance.
Heat Resistant

Processing Guidelines – Injection Molding
Optimal results with PA12 LCF30 require proper drying, screw design, and mold temperature control to preserve long fiber length and maximize mechanical performance.
Step 1: Drying
Dry at 90- 110 °C for 3- 4 h with a desiccant dryer. Keep moisture <0.01% to prevent hydrolysis.
Step 2: Processing
Set nozzle melt temp 210- 240 °C, mold temp 40-60°C. Use slow-moderate injection speed at 80-115 MPa.
Step 3: Tooling Notes
Use a low-compression screw, full round runners & large gates. L/D ratio 18:1-24:1, clamp force >100T.
