We specialize in the production of E type rail insulators and guide plates, meticulously crafted for the SKL rail fastening system and Nabla fastening system. Our insulators are made from high-quality PA66 material in a choice of classic shades: white, dark brown, and black. These expertly engineered nylon insulators are essential for adjusting rail gauge and effectively insulating the rail from ties and clips, ensuring a robust and secure track operation.
Below are the detailed material properties of PA66, which emphasize its superior quality and reliability.
PA66: Composed of Nylon 66.69%, Glass Fiber 30%, Other additives 1%, this composition guarantees exceptional strength and durability.
