The primary material used for Tesla Model Y sunroof sunshades consists of a composite structure comprising a high-density polyester fiber base fabric, a metallized coating layer, and an electrostatic adsorption layer. This design balances thermal insulation, precise fit, and ease of use, having been engineered specifically for frameless panoramic glass roofs.
Outer Layer (UV-Resistant/Reflective Layer):
Utilizes vacuum-sputtered metallized coating (e.g., aluminum or silver alloy) to reflect over 60% of solar radiant heat. With a UV blocking rate approaching 99%, it effectively mitigates heat buildup inside the vehicle.
Middle Layer (Thermal Insulation Base Fabric):
Constructed from high-density polyester fiber (PET) with a thickness of approximately 0.3–0.5 mm. It offers excellent thermal stability and aging resistance, ensuring it remains free from deformation even after prolonged exposure to sunlight.
Inner Layer (Adsorption Layer):
Coated with an electrostatic silicone material, allowing it to adhere firmly to the glass without the need for adhesives or magnets. It is easy to install and remove without leaving any residue, thereby protecting the vehicle's original glass coating.
