The author was struggling with whether to choose a white interior before, so he inquired a lot of information to study the white interior. Share the information you found here.
Check the Tesla owner's manual to determine that the coating on the white interior is polyurethane. According to some information on the extranet (unofficial), the seat material is Ultralaeather provided by ultrafabrics manufacturers. And Ultraleather is not really cowhide, it is a synthetic polyurethane coated fabric (vinyl) that is used as a leather substitute. In order to accelerate the world's transition to sustainability, Tesla has two statements that the use of animal leather as a seat material began in 2015 or 2017, and riders who know the exact time can also share the following information.
Because Tesla's seats use artificial leather materials. Compared with animal leather, artificial leather will perform better in terms of material toughness and wear resistance.
Polyurethane is a general term for polymers containing carbamate groups in the main chain of macromolecules.
It has many advantages, with good oil resistance, wear resistance, aging resistance, toughness, viscosity and mechanical properties. Good thermal, sound insulation and seismic performance.
Because polyurethane has many excellent properties, it has a wide range of uses. Waterproof materials are also commonly used in house decoration, and can also be seen on the runways of sports fields and the indoor floors of buildings.
Disadvantages of polyurethane:
1. High temperature resistance is general, especially the damp heat resistance is not good. The normal operating temperature range is -40 ~ 120 °C.
2. Not resistant to strong polar solvents and strong acid and alkali media. At a certain temperature, alcohols, acids, etc. will make the polyurethane elastomer swelling and degradation, chloroform, dichloromethane, dimethylformamide, trichloroethylene and other solvents at room temperature will make the polyurethane elastomer swelling.
3. Poor flame retardancy, fast combustion speed and the process will produce droplets, which will accelerate the spread of fire. And polyurethane also produces toxic gases when burned, mainly carbon monoxide (CO).
Knowing the advantages and disadvantages of polyurethane, we can also know what to pay attention to when using white interior coatings.
Pay attention to tram Li Bai, the next article shares how to maintain the white interior and some precautions.
