What are the materials of different parts of the Xiaomi Microwave Oven?

1. The inner (cavity) of the microwave oven utilizes cold rolled sheets with epoxy coating, which can tolerate high temperatures and microwaves well;
2. The oven door and observation window utilize tempered glass, which is heat-treated, making it about 4x stronger than regular annealed glass;
3. The glass tray is made of silica, which has very high thermal shock resistance. It will not crack even if heated to very high temperatures;
4. There is a mica plate on the back of the oven, serving as a waveguide mask. The mica plate prevents food and contaminants from reaching the electrical components;
5. The material of the heat insulation sheet is PET (also abbreviated PETE), which is short for polyethylene terephthalate. PET material is non-toxic, safe, environmentally friendly, and has many advantages like heat resistance, chemical resistance, electrical insulation, and so on;
6. The door frame seal is made of ABS (Acrylonitrile-Butadiene-Styrene), which is an opaque thermoplastic. It has good heat resistance and toughness.
