Products Description: Shell Material: 100% of PET and 30% of Glass Fiber,environmental protection, fireproofing thermal stability up to 240 centigrade Heating Unit: MCH Heating Panel: The heating panels are painted with Ceramic Paste imported from Korea; it can generate infrared ray and negative ions which can protect and rehabilitate hair; the paint does not peel off after 40 thousand continuously straightening. Warm-up Time: 1.Generating heat in 5 seconds and up to 200 centigrade in 60 seconds 2.NTC temperature-sensing element and high-temperature fuse,it not only can warm up fast, but keep your safety Temp. Control: The internal circuit boards are original dual circuit boards using original NASA IC; it is accurate and steady in controlling temperature; the switch takes two-row switch(L (wire under voltage), N(neutral)); there is no current on the boards after switching off so that can avoid getting an electric shock. Performance: 1.Automatically warming up at 200 centigrade when power on and power off after 30 minutesif no one use it; 2.Ergonomics Design, comfortable for operating; 3.Far infrared tech and microcoptuer for controlling temperature more accurately and evenly; 4.Easy operation of switches, auto-safety apparatus fitted in the circuit board for cutting off electricity when creepage Voltage & Plug: 1.Voltage AC110V/60Hz-240V/50Hz,available for every country; 2.Plug: by customers' requirements Power Line & Tail: The power line takes 360 rotation designs; the internal sheet copper takes gilding technics which is in high safety factor
