What type of film is Crystalline 70?
2 Answers
Crystalline 70 is a premium product in 3M's automotive heat insulation film series. Here are the relevant details: 1. Production technology: The 3M Crystalline 70 heat insulation film adopts bionic principles inspired by the wings of the Morpho butterfly. It utilizes "ultra-fine coating technology" to apply over 200 layers of nano-microstructures onto polyester substrates. Each layer can selectively reflect infrared rays, and through over 200 reflections, the majority of heat is reflected outside the vehicle, achieving thermal insulation. 2. Advantages: Bionic principle containing over 200 layers of nano-microstructures; outstanding thermal insulation performance with selective infrared reflection; non-metallic material that doesn't block electromagnetic signals, with no fading or corrosive oxidation.
Jingrui 70 belongs to the category of automotive window films, specifically a high-end model designed for car window tinting. With a light transmittance rated at 70%, it allows 70% of visible light to pass through, ensuring clear visibility during night driving or rainy conditions. This film excels in heat insulation, effectively blocking most infrared and ultraviolet rays, significantly reducing interior temperatures during summer and lessening the burden on air conditioning. In terms of brand, Jingrui is a well-known product among domestic film brands, emphasizing clarity and durability in its design. After personal use, I found it more long-lasting compared to standard films, and professional installation can prevent bubble issues. When selecting a film, it's important to match the vehicle model. A 70% transmittance is ideal for front windshields, though darker films offer slightly better heat insulation. Budget-wise, it offers good value for money and is worth considering.
