September 21, 2026 – Guangdong, China – Guangtong Plastics, a global leader in high-performance modified plastic solutions, today announced the successful launch of a newly upgraded PC/PMMA/PS infrared-transparent material designed to address key challenges in advanced intelligent driving perception systems. Engineered to meet the growing demand for automotive infrared optical systems, this material marks another significant breakthrough for Guangtong Plastics in the field of specialty engineering plastics for intelligent vehicles.
As the automotive industry advances toward high-level autonomous driving, there are increasingly stringent requirements for the precision and reliability of environmental perception systems. Core sensors—such as LiDAR, infrared night vision systems, and in-cabin Driver Monitoring Systems (DMS)—must operate reliably under complex lighting and extreme weather conditions. However, traditional transparent materials often struggle to balance visible light masking with efficient transmission of specific infrared wavelengths, creating a bottleneck for sensor performance enhancement.
Guangtong Plastics’ new PC/PMMA/PS infrared-transparent material solves this challenge through a unique blend-modification process. The material exhibits exceptionally high transmittance and extremely low absorption in the 600–950 nm near-infrared range, effectively allowing infrared light to pass through and ensuring that LiDAR and infrared cameras capture clear environmental data under various lighting conditions. Additionally, the material offers excellent transmission performance within specific spectral ranges (typically 3–5 μm or 8–12 μm).
Beyond its superior optical properties, the material boasts outstanding mechanical strength and environmental durability. It effectively balances visible light blocking, thereby protecting occupant privacy while granting automotive designers greater freedom in exterior styling. Its high weather resistance and impact strength ensure stable performance for sensor housings, even when exposed to prolonged sunlight and rain or impacts from road debris during high-speed driving. "We are delighted to announce the mass production of this infrared-transparent material at Guangtong Plastics," said the company's product manager. "Leveraging our extensive expertise in materials R&D, this innovative PC/PMMA/PS infrared-transparent material not only meets the automotive industry's rigorous standards for quality, safety, and reliability but also offers an innovative, integrated solution for autonomous driving sensing systems. We remain committed to accelerating the application of advanced materials and driving the future of mobility."
Currently, this PC/PMMA/PS infrared-transparent material has passed stringent testing by several leading Tier 1 suppliers. It is scheduled for official application in the fourth quarter of 2026, specifically for LiDAR covers and DMS infrared camera modules in next-generation smart vehicle models.
In addition to infrared-transparent materials, Guangtong Plastics boasts a comprehensive product portfolio in the field of specialty engineering plastics—including PC materials for laser protection, blue-light blocking, light guidance, and thermal insulation—dedicated to providing global customers with tailored, industry-compliant plastic solutions.
