Graphene PTC Heating Solutions for Portable Device Manufacturers

Self-Regulating Temperature Control & Safety

The graphene PTC material automatically adjusts resistance with temperature (R80/R25≥100), limiting power output to prevent overheating. With a lifespan >30,000 hours and leakage current <1mA (at 1000V DC), it ensures safe operation in extreme conditions (-40°C to 100°C).

Customizable High-Performance Parameters

Operates across 3.0-1000V DC with power density 0.05-1.5 W/cm². Customizable dimensions (<1000mm length, <400mm width) and insulation materials (PI/silicone) for diverse applications like EVs, aerospace, and medical devices.

Eco-Friendly Industrial Scalability

Uses water-based, non-toxic intercalation liquid-phase exfoliation technology for mass production. Automated production lines reduce energy consumption by 30% (ISO 14001-certified), enabling cost-effective, green manufacturing of graphene materials.

Smartphone OEMs

Challenge: Users in Nordic markets experience 40% faster battery drain in winter.

Solution:
• Graphene heater layer bonded to battery casing
• Maintains 15–25°C optimal operating range
• Reduces cold-related warranty claims by 60% (based on beta testing)

Drone Manufacturers

Challenge: Industrial inspection drones lose 50% flight time in cold environments.

Solution:
• Custom-shaped heaters for LiPo battery packs
• Enables stable operation at -30°C (ideal for oil/gas pipeline monitoring)

Wearable Tech Brands

Challenge: Fitness trackers fail during winter sports activities.

Solution:
• Flexible heating film for curved surfaces (e.g., smartwatch backs)
• Dual function: Battery optimization + user comfort (adjustable via app)
