Type : All kinds available according to customers drawings and samples .
Raw material : PA66 .
Surface : plain (oil)
We produced many kinds of rail insulators , the material we use is PA66 , with the color
white/dark brown /black , Insulators are used to adjust rail gage and insulate rail from ties
and clips .
The material properties of PA66 is below:
PA66 : Nylon 66.69%, glass fiber 30%, other 1%
