1) Straighteners can be categorized into ceramic heating element, PTC heating element and MCH heating 

element according to the different heating elements.The advantages of ceramic heating element are 

environmental protection and fast heating speed.In general, the surface temperature of the splint can reach 

200 degrees in 30 to 45 seconds. However, since the ceramic heating element is sintered at a high temperature 

of over 1000 degrees, its temperature will quickly exceed 300 degrees after the circuit is out of control, which 

will burn the plastic material that holds the heating plate in place and cause it to burn out. It may come into 

contact with the user and burn the skin after falling.

PTC stands for PositiveTemperatureCoefficient, which translates to Positive Temperature Coefficient, or PTC 

thermistor for short.PTCs are also sintered at high temperatures, but the maximum temperature of their 

surfaces during sintering is controlled. Depending on the manufacturer's requirements, the surface can be 

sintered at temperatures below 280, or at any temperature the manufacturer requires, generally sintered to 

230 degrees to 280 degrees. The disadvantage, however, is that the temperature is slow to rise to 200 degrees, 

usually taking about a minute and a half or two minutes. Also, in use, it does not maintain a consistently high 

temperature like ceramic heaters. The effect of straightening hair is slightly worse.

(2) According to the different materials of the heating plate, the hair straightener can be divided into: pure 

ceramic heating plate, aluminum plate with ceramic glaze sprayed on the surface, microcrystalline glass plate. 

The advantages of ceramic heating plate are environmental protection, good heat preservation performance, 

good safety. The disadvantages are long processing cycle, many processing steps, and because the edges are 

difficult to deal with and very smooth, it will slightly pull the hair in the process of straightening hair.

The advantage of spraying a ceramic glaze on an aluminum plate is that it is easy to produce. In addition, due 

to mechanical molding, the edges are smooth and do not pull on the hair. Hair extensions also work well 

because the surface is sprayed with ceramic glaze. The disadvantage is that because it is metal, it is not 

insulated, and the internal heating element must be insulated to avoid the safety hazard caused by leakage.

Microcrystalline glass plate application is less, mainly because its surface smoothness is not as good as 

ceramic glaze, not easy to molding fixed, so you must redesign the product structure.

(3) hair straighteners are distinguished from the structure. Generally divided into V-type and X-type. Early 

more popular X-type, recently more popular V-type. Because the V-type hair straightener can not only 

straighten hair, but also can be used for curling hair. More and more hairdressers use hair straighteners for 

curling hair.

4) According to different power sources, hair straighteners are divided into wired hair straighteners and 

wireless charging hair straighteners. Corded hair straighteners are hair straighteners that work by connecting 

to the mains power supply. Cordless rechargeable hair straighteners use a charger. Charge the rechargeable 

battery and use the battery as a power source. The advantage of a wired hair straightener is that it can work 

continuously. The disadvantage is that the hair straightener design and production process can be a safety 

hazard if the control is not reasonable. In addition, it is inconvenient to carry the power cord with you when 

you use it. The advantage of wireless hair straightener is safety, because it is branch circuit power supply, easy 

to carry when traveling.

5) Hair straighteners can be categorized into wide-plate, medium-plate, narrow-plate and miniature by size.

The length of the hair straightener of the wide-plate hair straightener is generally 90MM and the width is 42MM, 

the length of the medium-plate hair straightener is generally 90MM and the width is 24MM, the length of the 

narrow-plate hair straightener is generally 80-90MM and the width is 13-14MM, and the length of the mini hair 

straightener is generally 60MM and the width is 13-14MM.

(6) hair straightener according to the type of hair extension classification, can be divided into ordinary and wet 

and dry type. Ordinary hair straightener pull hair must be blow-dried to start pulling, wet and dry type can pull 

wet hair. Wet and dry hair straightener hair straightener should have 8-10 air holes, so that water can become 

steam from the air holes.

7) Voltage and export country classification, plugs include Chinese plugs, European plugs, American plugs 

(American leakage protection plugs), Australian plugs, Japanese plugs, German electric plugs, South African plugs,

British plugs and other plugs. Voltage: 110V-240V universal voltage is also available, only for specific countries, 

specific voltage or current
