GC-Type Polyimide Carbon-Based Film – High-Performance Precursor For Artificial Graphite Films

Product Overview

 
Our GC-Type Polyimide Carbon-Based Film is a biaxially stretched, high-carbon-yield PI film engineered specifically for manufacturing artificial graphite films through high-temperature graphitization (up to 3000°C). With ultra-high molecular orientation and optimized imidization, it delivers superior dimensional stability and carbonization efficiency—critical for thermal management materials in electronics, aerospace, and energy storage.

Key Features

✔ Controlled Carbon Yield (≥65%) – Maximizes graphite output
✔ Biaxial Stretching (MD/TD 3:1 ratio) – Ensures uniform crystal alignment
✔ Low Ash Content (<50ppm) – Minimizes impurities for high-purity graphite
✔ High-Temp Stability (≤450°C pre-carbonization) – Prevents premature degradation
✔ Customizable Thickness (25-125μm) – Tailored for target graphite density

Applications

• Artificial Graphite Films – Heat spreaders for 5G/LED devices

• Fuel Cell Components – Gas diffusion layers (GDLs)

• Lithium-Ion Batteries – Anode current collectors

• Satellite Components – High-purity thermal interfaces

• Semiconductor Tools – Wafer processing carriers
