What Are the Differences Between Good and Bad Automotive Explosion-Proof Films?
2 Answers
There are several key differences between good and bad automotive explosion-proof films: 1. Light transmittance: High-quality front windshield films should have a light transmittance of over 80%, while side window films should ideally have a light transmittance of more than 35%. 2. Scratch resistance: Premium films feature a scratch-resistant layer that protects the surface from damage under normal use; lower-grade films are more prone to scratches, leading to reduced clarity. 3. Explosion-proof performance: Inferior films are thin, feel soft, lack sufficient toughness, cannot block UV rays, and are prone to aging and brittleness. In the event of an impact or collision, they easily break and fail to adhere to the glass. High-quality explosion-proof films use special polyester materials with strong toughness and are paired with pressure-sensitive adhesives, ensuring that the film remains bonded to the glass during collisions to prevent shattering and injury.
With over a decade in auto repair, I can judge window films as easily as reading people. Quality films use metal sputtering technology – your car cools down within ten minutes of AC use in summer. Cheap films just spray dye that fades and bubbles within months. The critical difference is shatter resistance: premium PET-based films retain over 90% of glass fragments during collisions, while inferior ones shatter into deadly shards. Then there's light transmission – windshield films must maintain over 70% visibility for safety, yet some substandard films make night driving like peering through fog. I've seen countless budget no-name films leave adhesive residue for half a year during removal, even damaging rear defroster wires. Always choose ISO-certified films with at least 5-year warranties if you're getting them installed.
