Rail Insulator
Discover the art of precision with our expertly crafted E-type rail insulators and guide plates, meticulously tailored for the SKL rail fastening and Nabla fastening systems. Each insulator is a masterpiece of engineering, fashioned from premium-grade PA66, and is available in a sophisticated palette of pristine white, deep dark brown, and timeless black. These rail nylon insulators are not just components; they are vital instruments for precise rail gauge adjustment, providing seamless insulation between the rails, ties, and clips, and ensuring unparalleled performance.
Below are the remarkable material properties of our state-of-the-art PA66.
PA66 Composition: A robust blend of Nylon 66.69%, fortified with Glass Fiber 30%, and enhanced with Other 1%.
