Flame-Retardant Graphite Film

Flame-retardant graphite film is made from high-purity flake graphite as the base material through an integrated process of intercalation expansion, calendering and flame-retardant modification. Its core advantage lies in balancing "high thermal conductivity" and "high flame retardancy" - it not only retains the excellent in-plane thermal conductivity of graphite materials to effectively solve equipment heat dissipation problems, but also achieves high-level fire protection through professional flame-retardant modification, avoiding fire risks caused by high temperature or overload. It is a preferred flexible film material for "both heat dissipation and safety" in multiple fields currently.

1. Graded Flame Retardancy for Full-Scenario Safety Needs

Based on application requirements, multi-level flame retardant effects are achieved through differentiated modification processes:

Basic Grade: Meets UL94 V-0 flame retardant standard, suitable for general scenarios such as consumer electronics;

Enhanced Grade: Improves high-temperature ignition resistance on the basis of UL94 V-0, suitable for high-temperature working conditions like new energy vehicle electronic control systems;

Premium Grade: Combines high flame retardant grade and excellent oxygen index performance, suitable for high-risk scenarios requiring thermal runaway prevention such as energy storage battery packs;

Adopts in-situ composite technology of nano flame retardants to ensure stable and non-migratory flame retardant components. The flame retardant performance does not significantly degrade after long-term use, which is superior to ordinary coated flame-retardant films.

2. High Thermal Conductivity + Low Thermal Resistance for Outstanding Heat Dissipation Efficiency

Optimizes the thermal conductivity anisotropy of graphite layered structure, with excellent in-plane thermal conductivity and low thermal resistance, far superior to traditional flame-retardant thermal pads;

The film thickness can be flexibly adjusted, and it can closely fit irregular surfaces such as chips and battery tabs, reducing heat dissipation loss caused by air gaps and improving equipment heat dissipation efficiency.

3. Flexibility and Fold Resistance for Complex Installation Scenarios

Possesses good mechanical stability and strong fold resistance. The thermal conductivity and flame retardancy remain basically stable after multiple folds;

Supports processing methods such as die-cutting and blanking, and can be made into various special-shaped parts, adapting to the miniaturization and integration design needs in 3C, automotive electronics and other fields.

4. Strong Temperature and Weather Resistance for Extreme Working Conditions

Has a wide operating temperature range for long-term use, capable of withstanding environments from low to high temperatures, and can withstand higher temperature shocks in the short term. The thermal conductivity and flame retardancy remain stable at high temperatures;

Possesses good resistance to damp heat and salt spray. When used in harsh environments such as automobile cabins and outdoor base stations, there is no delamination or corrosion, showing strong adaptability.

5. Environmental Compliance for Global Market Access

Free of heavy metals, polybrominated biphenyls (PBBs) and other harmful substances, complying with international environmental standards such as RoHS, REACH and California Proposition 65;

Low VOCs emission, meeting the strict air quality requirements for indoor electronic equipment and automotive interior parts.
