MMA side-glowing optical fiber, also known as whole-body luminous optical fiber, is commonly referred to as UC light guide in the field of automotive interior lighting and electronic products, as well as lighting optical fiber in architectural decorative lighting. its most prominent light-emiting characteristic is that the entire fiber emits light uniformly. Compared with traditional point-source optical fibers, it offers more uniform luminosity, higher flexibility, and pliability, allowing for easy bending and twisting. In terms of material, the outer sheath is made of Teflon, which is resistant to acids, alkalis, and high temperatures, while the inner core is a highly light-conductive polymer formed by high-temperature and high-pressure injection molding, ensuring stable performance and efficient light transmission.
