GUANGDONG, China — October 19, 2026 — As the global automotive industry accelerates towards autonomous driving and the manufacturing sector increasingly relies on high-precision laser processing, the need for advanced, highly specialized safety materials has never been greater. Today, Guang Tong Plastics, a leading innovator in modified polymer materials, officially announces the commercialization of its latest breakthrough: PC Laser Protective Granules.
This new specialized engineering plastic is specifically formulated to address the critical safety and performance challenges posed by modern laser technologies, particularly in the rapidly expanding fields of LiDAR (Light Detection and Ranging) and industrial laser protection.
Uncompromising Safety Meets Optical Clarity
Unlike traditional opaque protective materials, the new PC laser protective granules from Guang Tong Plastics strike a perfect balance between maximum laser attenuation and optical transparency. According to extensive laboratory testing, the material achieves a Near-Infrared (NIR) blocking rate of over 99.8%, effectively shielding human eyes and sensitive optical sensors from harmful laser radiation.
Simultaneously, the material maintains a visible light transmittance rate of over 60% (within the 400–700 nm range). This high level of clarity is crucial for LiDAR covers and automotive sensor windows, ensuring that the visible light required for cameras and human vision is not compromised while blocking the invisible, high-energy NIR wavelengths used by LiDAR systems.
Furthermore, the product provides comprehensive protection across the ultraviolet, visible, and near-infrared spectrum (180 nm to 1 mm). This broad-spectrum defense ensures high mechanical reliability and optical stability under various environmental conditions.
Meeting Global Industry Standards
As laser safety regulations tighten worldwide, Guang Tong Plastics’ new material has been rigorously engineered to comply with the most stringent international benchmarks. The PC laser protective granules fully meet the requirements of GB 30863 (Chinese National Standard for laser protective eyewear and materials) and EN 12254 (European Standard for laser protection), making them ready for global deployment.
"With the proliferation of autonomous vehicles and automated industrial laser cutting systems, the margin for error in laser safety is zero,"General Manager of Guangtong Plastics said. "Our new PC laser protective granules are a testament to our commitment to material science innovation. By solving the contradiction between high visible light transmission and absolute NIR blocking, we are empowering OEMs and Tier 1 suppliers to design safer, smarter, and more reliable products."
Versatile Applications Across Industries
The newly launched PC laser protective granules are ideal for a wide array of demanding applications, including:
-
Automotive LiDAR Housings & Covers: Protecting external and internal sensors from environmental damage while ensuring peak sensor performance.
-
Laser Safety Goggles and Face Shields: Providing transparent, lightweight, and highly durable protection for industrial workers and medical personnel.
-
Optical Sensor Windows: Used in robotics, drones, and military optical equipment.
With its state-of-the-art manufacturing capabilities and a dedicated R&D team, Guang Tong Plastics continues to push the boundaries of special engineering plastics, offering customized solutions that meet the evolving needs of global clients.
