Guarding the original sound texture, casting the quality protection-GB618B protective film, the exclusive guardian of the stainless steel horn net of the car speaker

For car audio and video enthusiasts, car speakers are not only the carrier of auditory enjoyment, but also the standard of quality travel. As the "first line of defense" of the speaker, the integrity of the stainless steel speaker net directly affects the sound quality performance and service life of the speaker. In the process of automobile production, transportation, assembly and daily use, the horn net is inevitably attacked by scratches, dust and oil, so a suitable protective film becomes the key to quality protection. GB618B protective film precisely matches the protection requirements of stainless steel horn net of automobile speakers, escorts every inch of horn net with excellent performance in all dimensions, so that the original sound texture is not discounted.

Accurate and adaptable thickness design is the fundamental prerequisite for protection. The GB618B protective film adopts a gold thickness of 60 microns, which can form a solid protective barrier, effectively resist external scratching and dust adhesion, and perfectly balance protection and sound quality assurance. The unique blue appearance not only has clear recognition and facilitates process differentiation and quality inspection traceability in the production process, but also adds an elegant visual protection to the horn net, avoiding confusion and misoperation during transportation.

The precise control of adhesion is the core advantage of protective film. The GB618B protective film has a suitable adhesive force of 300-500g, achieving the ideal effect of "sticking firmly and tearing cleanly". In the complex production and transportation environment of automobiles, it can tightly adhere to the surface of stainless steel horn mesh, without curling or falling off, firmly blocking the invasion of dust and oil stains; And when it needs to be torn off, it can be easily peeled off without any residual glue, without the need for additional cleaning, perfectly maintaining the metallic luster and surface cleanliness of the horn mesh, saving a lot of trouble for subsequent assembly.

Excellent mechanical performance, suitable for the entire process of automotive production testing. Its tensile strength reaches 16MPa in the MD direction and 11MPa in the TD direction, coupled with a high elongation of 300% in the MD direction and 550% in the TD direction, allowing the protective film to synchronously follow the deformation during the stamping, bending and other processing of the horn mesh, without cracking or tearing, achieving full wrap protection. At the same time, the Young's modulus of 150MPa in the MD direction and 230MPa in the TD direction endow the protective film with just the right amount of rigidity and flexibility, which can resist mechanical impacts during processing and adhere to the complex surfaces of the horn mesh, ensuring no blind spots in protection.

Extreme environmental tolerance demonstrates the reliable quality of the product. GB618B protective film can withstand extreme temperatures ranging from minus 10 degrees to 60 degrees Celsius. Even in such a temperature difference environment for 24 hours, it still maintains stable performance. After tearing off, there is no residual glue or corrosion, effectively avoiding damage to the horn mesh caused by low temperature brittleness, high temperature overflow, and other problems. Whether it's the harsh winter in the north or the scorching summer in the south, it can always hold its protective post and ensure that the horn net remains intact.

Scientific ratio of optical performance, balancing protection and practical needs. With a haze of 26% and a penetration rate of 55%, the GB618B protective film not only achieves effective protection but also does not excessively block the metallic texture of the horn mesh, maintaining the aesthetic appearance of the product. Assist in maintaining the purity and clarity of sound quality, ensuring both protection and auditory experience.

The quality control of every link from production and processing to end use determines the ultimate experience of car speakers. GB618B protective film provides comprehensive performance that accurately matches the stainless steel horn mesh requirements of automotive speakers, covering all protection details to ensure quality assurance. Choosing GB618B means choosing a reliable protection system that ensures every car speaker is in its best condition, providing users with a pure auditory feast and injecting solid assurance into the quality of car audio and video.
