With the widespread adoption of consumer smart products—such as robot vacuums, smart projectors, and VR/AR devices—the number of laser and infrared radiation sources in home environments has risen significantly, making eye safety and device protection a shared priority for both consumers and manufacturers. Infrared optical materials based on PC (polycarbonate)—specifically PC/PMMA/PS blends—are rapidly transitioning from industrial applications to everyday home life; thanks to their exceptional impact resistance and precise laser-blocking capabilities, they have become indispensable, invisible safety shields for smart devices.

Driven by the explosive growth of the new energy vehicle and smart home industries, material lightweighting and high safety have become core demands within the sector. Thanks to their excellent impact resistance, heat resistance, and high transparency, polycarbonate (PC) materials are increasingly replacing traditional metals and glass. This article explores the innovative applications of modified PC materials in areas such as charging piles, automotive lighting, and smart device panels, as well as the future technological evolution of the industry.

      Guangdong, China – September 21, 2026 – Guangtong Plastics announced today that it has achieved key technical upgrades and scaled mass production for its proprietary infrared-transparent PC/PMMA/PS materials. Featuring exceptional infrared transmittance and visible light shielding capabilities, these materials are set for widespread application in LiDAR covers for autonomous driving, in-cabin Driver Monitoring Systems (DMS), and infrared camera modules, providing safer, more precise, and all-weather environmental sensing solutions for smart vehicles.

PC/PMMA/PS Matting plastic is a specialized optical-grade engineering plastic produced through the precise blending and modification of three base resins: polycarbonate (PC), polymethyl methacrylate (PMMA), and polystyrene (PS). It combines the performance advantages of these three materials, offering excellent light transmission, a high refractive index, and high impact toughness, alongside resistance to weathering, aging, heat, and corrosion, as well as ease of processing. Capable of directly replacing traditional glass and single-resin optical materials, it serves as a lightweight upgrade solution for optical components in sectors such as lighting, displays, automotive, and electronics.

Against the backdrop of the comprehensive construction of digital traceability systems in industrial manufacturing and the continuous upgrading of global safety compliance standards, permanent product traceability and fire resistance of structural components are becoming mandatory entry requirements in fields such as electronics, automotive parts, and industrial equipment. Traditional surface marking methods such as screen printing, pad printing, and labeling have inherent shortcomings, including easy wear and tear, poor resistance to solvent corrosion, and easy damage to the flame retardant properties of the substrate, making them difficult to adapt to stringent industrial conditions and safety certification standards. Guangtong Plastics' flame-retardant laser-engraved PC material deeply integrates laser marking functionality with a highly efficient flame-retardant system through bulk blending modification technology. While fully preserving the excellent mechanical properties of polycarbonate, it simultaneously achieves high-contrast permanent engraving and industrial-grade fire safety, providing an integrated material solution of "marking traceability + fire protection" for industrial components.

PC cold-resistant material is a functional engineering plastic made from polycarbonate (PC) resin as the base material and modified with a highly efficient cold-resistant toughening system. While retaining the inherent advantages of PC base material, such as high rigidity, dimensional stability, ease of processing, and electrical insulation, it completely solves the industry pain points of ordinary PC being prone to embrittlement and a sharp drop in impact performance under low-temperature environments. It can maintain excellent impact toughness at extreme low temperatures of -40℃, while also taking into account wide temperature range applicability and good weather resistance. It is an upgraded replacement material for structural components in low-temperature scenarios such as cold chain, outdoor engineering, and high-altitude equipment.

PC antistatic crystal is a functional modified engineering plastic made from PC resin as the base material, improved through the addition of a high-efficiency antistatic functional system and a blending process. As a core structural material in industrial electrostatic protection scenarios, it can quickly dissipate accumulated static charge on surfaces, preventing static buildup, dust adsorption, and the hazards of electrostatic discharge, while fully retaining the inherent high impact resistance, dimensional stability, and ease of processing of PC. It is an upgraded alternative to traditional coated antistatic materials and ordinary antistatic plastics.

PC thermal insulation material is a functional engineering plastic made from polycarbonate (PC) resin as the base material and modified with nano-inorganic metal oxides. While retaining the inherent advantages of PC substrates such as impact resistance, lightweight, and ease of molding, it achieves the dual characteristics of high visible light transmittance and efficient infrared heat blocking. It can effectively block heat transfer from infrared radiation for a long time while maintaining a high-definition optical effect with extremely low haze. It is an upgraded alternative for thermal insulation structural components in the automotive, electronics, and industrial equipment fields.

By precisely controlling the ratio of additives and the refractive index of the substrate, light guide particles optimize the light diffusion effect while ensuring high transmission efficiency. They can transform point light sources and line light sources into uniform and soft surface light sources, effectively reducing glare, dark spots and light energy loss. They are suitable for various design schemes such as side-lit backlights and irregularly shaped light guide structures.
