Introduction to halogen-free PC

Introduction to halogen-free PC materials: In the modern electronics and electrical industry, the use of plastic materials is ubiquitous. One widely used engineering plastic is polycarbonate (PC). However, traditional PC materials contain a certain amount of halogen elements, which release toxic gases during combustion, posing a potential threat to the environment and human health. Therefore, in recent years, environmentally friendly and halogen-free PC materials have gradually been favored by the market. This article will focus on introducing this new environmentally friendly “halogen-free PC” material and its characteristics. What is a halogen-free PC? Halogen-free PC refers to polycarbonate materials that do not contain halogens (Fluorine fluorine, Chlorine chlorine, Bromine bromine, Iodine iodine, and Astatine astatine). Compared with traditional PCs, it eliminates the negative impact of halogens while maintaining its original excellent performance, which is more in line with the requirements of green manufacturing. The characteristics of halogen-free PC and its flame retardant performance: Although it does not contain halogens, by adding other non-toxic and efficient flame retardants, halogen-free PC can still meet the UL-94 V0 level standard, which is the level of self extinguishing. Mechanical strength: Halogen free PCs have high impact resistance and fatigue resistance, making them suitable for situations that require strong mechanical strength. Weathering resistance: It can operate over a wide temperature range and has certain UV protection capabilities, making it suitable for outdoor application environments. Transparency: Halogen-free PCs have a high transmittance and are not affected by temperature, making them widely used in optical equipment. Processability: Halogen free PC can be processed through injection molding, extrusion molding, and other processes, with good dimensional stability. Environmental friendliness: Due to the absence of harmful substances, halogen-free PCs are more easily recycled or degraded after disposal, reducing environmental pollution. The application field of halogen-free PC in the electronic and electrical industry: used for producing various insulation components, connectors, switch panels, etc., meeting strict fire and safety standards. Automotive industry: It has related applications in the fields of vehicle interior decoration, headlight housing, bumper, etc. Construction industry: used for making window frames, skylight covers, etc., which are both aesthetically pleasing and safe. Medical equipment: Due to its biocompatibility and easy disinfection characteristics, halogen-free PCs are commonly used in the production of medical devices. Aerospace: In high-tech aircraft, such as cockpit glass, radar antenna covers, etc., halogen-free PC materials are required. With the continuous improvement of global environmental awareness and the strengthening of social responsibility, the halogen-free PC market will continue to expand in the future. At the same time, R&D personnel are constantly exploring more advanced technologies to improve the performance of halogen-free PC materials, in order to adapt to more diverse and higher demand industries. For example, developing new additive systems to improve the toughness, thermal stability, and chemical corrosion resistance of materials. As an environmentally friendly engineering plastic, halogen-free PC not only meets the urgent need for sustainable development in today’s society, but also provides safer and more reliable material choices for various industries. With the advancement of technology and market recognition, it is believed that halogen-free PCs will play an increasingly important role in future development.
