1. Advantages:
1. Heat up quickly. The aluminum sheet is more compact and has higher thermal efficiency.
2. Healthy and environmentally friendly glueless bonding is more healthy.
3. Ultra-long durable and non-oxidizing, with a service life of up to 6000 hours.
4. The thermal efficiency of PTC heating element is as high as 99%.
2. Disadvantages:
1. No energy saving.
2. Metal electric heating materials, easy to oxidize at high temperature, power attenuation, and short service life. Because its metal has a flat surface, it has a larger air contact area and has a shorter life span than a metal wire.
