Features: 1. Alloy heating wire: The heating wire consists of more than ten copper-nickel alloy wires and a 500D high-strength pull and anti-ballistic wire. Each of the ten copper-nickel alloy wires is independent, and if one of them is cut, the product can work normally. 2. Safe to use: Alloy heating wire, intelligent temperature control, frost protection wire, switch plug, high temperature plug, anti-slip back, plush fabric, easy to install. 3. Cold and durable: Frost protection wire is specially designed for extremely cold regions. The cold-resistant cable has the properties of wear resistance, cold resistance, tear resistance and high flexibility. It has good cold resistance and long-term use in low temperature environments without embrittlement and cracking. 4. High temperature resistant flame retardant plug is safer to use Anti-slip particles on the back can effectively reduce seat cushion dislocation to increase safety and comfortable driving. Plush fabric is delicate and smooth, warm and comfortable, long-lasting warm for travel. 5. Intelligent temperature control is safer If the seat cushion is heated to 60 C, the temperature control switch will turn off automatically and the heating pad will no longer work. When the temperature drops to 40 C, the thermostat will automatically close and start working again.
