(Guangzhou, China)​ Guangzhou Lingyinhang Composite Materials Co., Ltd. (hereinafter referred to as "Lingyinhang") has achieved a significant breakthrough in the field of new automotive materials. On June 28, 2024, the company was granted two invention patents by the China National Intellectual Property Administration on the same day. The two patents are respectively "A Scratch-Resistant Blackout Film for Automobiles and Its Preparation Method" (Patent No.: ZL202410329763.4) and "A Breathable Blackout Film for Automobiles and Its Preparation Method" (Patent No.: ZL202410338073.5) .The granting of these twin patents not only demonstrates Lingyinhang's strong continuous innovation capabilities but also signifies the company's leading achievements in solving two major industry pain points for automotive blackout films: "durability" and "functionality" .

I. Dual Breakthroughs: Precisely Addressing Core Demands in Different Application Scenarios

Although both patents belong to the automotive blackout film field, their technical focuses and addressed pain points have distinct emphases, forming a perfectly complementary profile and showcasing Lingyinhang's precise insight into market demands

Patent One: Scratch-Resistant Blackout Film – Pursuing Extreme Durability and Aesthetic Longevity

The core of this patent technology lies in significantly improving the surface scratch resistance and overall durability of the blackout film

On automobiles, blackout films are widely used on external visible parts such as window trim, grilles, and door frames, which are highly susceptible to scratches during car washing and daily driving, severely affecting appearance. Lingyinhang's invention, through unique material formula design and precise preparation processes, forms a dense and tough protective layer on the substrate surface that effectively resists external physical friction, maintaining a sleek black appearance for a long time . Its breakthrough aspect is that it overcomes the bottleneck of traditional blackout films being "easily scratched and difficult to maintain," providing automakers with an advanced material solution that meets higher quality requirements and enhances the vehicle's exterior durability .

Patent Two: Breathable Blackout Film – Innovatively Balancing Blackout Properties with Heat Dissipation/Pressure Equalization

This patent technology takes a different approach, focusing on solving derivative problems caused by blackout films in enclosed environments

For instance, when used to cover radar/sensor areas or areas behind lamp housings requiring heat dissipation, traditional non-breathable blackout films may impede the heat dissipation of electronic components or cause fogging due to pressure differences. Lingyinhang's invention creatively endows the material with good breathability while achieving efficient visual blackout . This ensures internal air circulation and moisture evaporation, guaranteeing the normal operation and long-term reliability of automotive components without compromising the uniformity and aesthetics of the exterior appearance . This holds extremely important application value in the current era of increasing sensors in smart cars.

II. Industry Breakthrough: A Leap from "Meeting Needs" to "Defining Standards"

The grant of these dual patents to Lingyinhang holds significance far beyond the accumulation of the company's own intellectual property, exerting a profound and positive impact on the industry:

Technical Leadership, Promoting Industry Upgrade:​ It elevates the performance indicators of automotive blackout films from basic "color and adhesion" to a new level of "functionalization," promoting an upgrade in the competitive dimension of the upstream material industry, shifting from price competition to technology competition

Empowering Customers, Enhancing Vehicle Quality:​ It provides automakers with a tool for differentiated competition. OEMs can use these high-performance materials to create more durable, reliable, and smarter new models suitable for the era of autonomous driving, directly enhancing the market competitiveness of end products

Building Barriers, Establishing a Leading Position:​ Protecting both the core technology and preparation method with patents builds a solid technical barrier, establishing Lingyinhang's position as a technical leader in the high-end automotive blackout film field and laying a solid foundation for future market expansion

III. The Source of Innovation: Rooted in a Customer-Centric R&D Philosophy

The inventor for both patents is the company's R&D engineer Chen Dong,reflecting that Lingyinhang possesses an elite R&D team that stays close to the market and excels at solving practical problems. The company consistently adheres to the development philosophy of "being customer demand-oriented and technology innovation-driven." By deeply integrating R&D with the market front line, it can so accurately identify and overcome common industry challenges.

In the future, Lingyinhang will continue to increase R&D investment, deepen the conversion of technological achievements in these two directions, and actively explore the development of other functional film materials, striving to become a trusted high-performance material partner for global automotive brands.
