For example, the automotive explosion-proof film industry is experiencing a surge in environmental innovation, starting with material innovation.
Let’s start with the new water-based polyurethane adhesive. It’s truly amazing! Using water as the dispersion medium, it reduces VOC emissions by over 90%, effectively cleansing the environment. Furthermore, it maintains a bond strength of 200-400 N/cm², fully meeting explosion-proof standards. LG’s explosion-proof film in South Korea uses this water-based adhesive and has even passed EU REACH environmental certification. Amazing!
We are also developing bio-based PET substrates. The company has launched a biomass PET film that uses ethylene glycol derived from sugarcane bagasse instead of petroleum-based materials, instantly reducing its carbon footprint by 40%. This film not only maintains a flexibility of 0.05-0.2mm but also achieves a UV blockage rate of over 99%, acting like a super sunscreen for your car.
Take a look at the heavy metal-free nanocoating. It utilizes non-metallic nano-ceramic particles like titanium dioxide, silicon dioxide, or titanium nitride to avoid contamination from metals like silver and aluminum. Furthermore, its infrared reflectivity exceeds 80%. Even more interesting, it doesn’t affect GPS signals, unlike metal coatings that tend to block them. This makes it ideally suited for the intelligent systems of new energy vehicles, essentially providing a seamless experience for the vehicle’s intelligent brain.
Having discussed material innovation, let’s look at environmentally friendly process innovation. UV light-curing technology is truly remarkable. It replaces high-temperature thermal curing processes, reducing energy consumption by 50%. It also prevents high-temperature denaturation of the adhesive layer and keeps the bubble rate to ≤ 0.1%, effectively giving the adhesive layer a meticulous maintenance treatment.
So what are the future innovation trends? First, there’s the exploration of biodegradable materials. In the lab, a polylactic acid (PLA)-based film has a decomposition rate of 90% within 180 days under specific composting conditions, essentially giving the film a “self-destruction” schedule. There’s also the integration of intelligent dynamic dimming films. Combining an electrochromic layer with an eco-friendly adhesive allows for intelligent adjustment of light transmittance between 5% and 80%, reducing the need for manual sunshades and making cars feel smarter. Ultra-thin designs are also a big draw. A nano-coating process reduces film thickness from the traditional 2.5mm to 1.5mm, reducing material usage by 40%—effectively slimming down the film.
Let’s take a look at a typical example: the environmentally friendly explosion-proof film solution for the Tesla Model 3. The bio-based skylight film uses a sugarcane PET substrate with a water-based adhesive, is only 0.1mm thick, reduces carbon emissions by 35%, and is recyclable within the warranty period. The all-ceramic side window film uses a nano-titanium dioxide coating, achieving 35% transmittance and reducing production wastewater toxicity by 90%. The electrochromic front windshield film incorporates a liquid crystal dimming layer and lead-free circuitry, reducing air conditioning energy consumption by an additional 18%. In actual measurements, the film’s lifecycle carbon emissions have been reduced by 50%, and it has also received international EPD environmental declaration certification. The results are truly impressive!
In general, the core principles of environmental innovation in automotive explosion-proof film lie in bio-based raw materials, such as sugarcane and PLA; clean production, such as with water-based adhesives and UV curing; and closed-loop recycling. Future technologies will focus on biodegradability and intelligent integration, propelling the industry from “high protection” to “zero carbon emissions.”
