Graphene Copper Foil Thermal Cooling Sheet, Self-Adhesive Graphene Heat Sink Pad for Phone, CPU, GPU, SSD & Electronic Chips

Product DescriptionOverview

This composite thermal sheet combines graphene layer + copper foil substrate, adopting dual-direction heat conduction design. Copper foil transfers heat longitudinally from heat sources quickly, while the black graphene layer spreads heat evenly in transverse direction, eliminating local hotspots effectively. It is a passive physical cooling solution for various electronics.

✨ Key Features & Advantages

1. Dual-layer high-efficiency heat dissipationCopper foil conducts heat rapidly from heat source; graphene layer homogenizes temperature across the whole sheet. Boost overall heat dissipation performance greatly and reduce thermal throttling.
2. Self-adhesive backing with release linerBuilt-in strong adhesive on copper side, just peel off the white/yellow protective release paper for easy attachment, no extra glue needed.
3. Insulated & non-conductive surfaceThe graphene side is non-conductive, avoid short circuit risk when directly pasting on chips and circuit boards.
4. Anti-oxidation & flame retardantGraphene coating protects copper foil from oxidation and discoloration. Flame-retardant property ensures long-term stable working.
5. Ultra-thin & flexibleThin and bendable, fits narrow internal space of mobile phones, laptops and compact devices. Easy to cut into custom sizes.
6. Wide temperature enduranceStable performance under continuous electronic device operating temperature, durable for long time use.

📌 Application Fields

• Smartphones: Gaming phone heat dissipation, reduce overheating during long gaming / video streaming
• Computer hardware: CPU, GPU, M.2 NVMe SSD, RAM, motherboard chips
• Portable electronics: Tablet, handheld game console, power bank
• Industrial components: PCB circuit boards, sensors, LED modules and small power electronics

📝 How to Use

1. Clean and dry the surface of your heat source (chip / phone inner shell) to remove dust and grease.
2. Peel off the protective release paper on the copper foil adhesive side.
3. Align and firmly stick the thermal sheet onto the target hot area. Press evenly for full contact.
4. Make sure the black graphene layer faces outward for heat radiation and uniform spreading.
5. Can be cut to required size with scissors for customized installation.

⚠️ Notes

• The copper foil side is conductive. Please avoid copper part contacting exposed circuit pins to prevent short circuit.
• Keep the sticking surface clean to guarantee good adhesive and thermal contact.
• It is passive cooling sheet, works better combining with external cooling structure if high power heat load.
