Rail Insulator
We produce E type rail insulator and guide plate for SKL rail fastening and Nabla fastening system. The material we use for rail insulator is PA66, with the color white, dark brown and black. Our rail nylon insulator is used to adjust rail gauge and insulate the rail from ties and clips.
The material properties of PA66 are listed below.
PA66: Nylon 66.69%, Glass Fiber 30%, Other 1%
