HDPE silicon core pipe is a new composite pipe with silicon gum solid lubricant on its inner wall,which is called silicon pipe for short.The main raw material is high density polyethylene,and the core layer is solid lubricant silicone with low friction coefficient.It is widely used in optical cable communication network system.The peak silicon core tube is a little bit:The silicon core layer on the inner wall is a solid lubricant;The silicon core layer on the inner wall of the pipe is extruded into the wall of the high density polyethylene pipe synchronously,and evenly distributed throughout the inner wall of the pipe,without peeling off or separation,with the same service life as the silicon pipe;The inner silicon core layer has the same physical and mechanical properties as HDPE;The friction characteristics of the inner silicon core layer remain unchanged,and the cable can be extracted repeatedly in the pipeline;The silicon core layer on the inner wall does not react with water,and the pipe can be washed with water after an accident.
