A 12V PTC Heater Element for Glue Gun is a small self-regulating heating component designed to provide consistent heat for melting glue sticks in hot glue guns. PTC heater elements are ceramic-based resistors that increase their resistance as temperature rises. Unlike traditional wire-based heaters, PTC elements are self-regulating, meaning they won’t overheat — they stabilize at a target temperature
Jaye Heater Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of 12v ptc heater element for glue gun in China, also supports custom service. Welcome to wholesale high quality 12v ptc heater element for glue gun at competitive price from our factory.
A 12V PTC Heater Element for Glue Gun is a small self-regulating heating component designed to provide consistent heat for melting glue sticks in hot glue guns. PTC heater elements are ceramic-based resistors that increase their resistance as temperature rises. Unlike traditional wire-based heaters, PTC elements are self-regulating, meaning they won't overheat - they stabilize at a target temperature. A 12V DC version is common in portable or battery-powered glue guns (e.g., for DIY, automotive, or craft uses). It's safer for low-voltage applications and can be powered from a battery pack, car socket, or DC adapter.

| Curie Temperature | 45°C–220°C | Common: 45°C (seats), 120°C (defrost) |
| Inrush Current | 8–10× steady-state | Lasts <0.5 seconds |
| Material | Aluminum shell with ceramic PTC chip inside | |
| Lifespan | over10,000hours | Automotive grade: 15,000+ hours |
At low temperatures, the PTC ceramic chip has a low resistance, allowing rapid heating when powered.
As the temperature approaches the rated working temperature (e.g., 180°C ~ 230°C), the resistance increases sharply, reducing the current and maintaining a stable temperature.
This self-regulating characteristic eliminates the need for additional temperature control circuits and prevents overheating.
1-Self-regulating design –automatic temperature control, prevents overheating2-Fast heating – melts glue sticks in 30–90 seconds
