HDPE Silicon Pipe HDPE Silicon Pipe also known as HDPE silicon core pipe is a composite pipe designed primarily to protect and install optical and electrical cables It features a unique construction where highdensity polyethylene HDPE forms the outer layer while the inner wall is lined with a silicone solid lubricant Product Description HDPE Silicon Pipe also known as HDPE silicon core pipe is a composite pipe designed primarily to protect and install optical and electrical cables It features a unique construction where highdensity polyethylene HDPE forms the outer layer and the core layer is made of solid lubricant silica gel with the lowest friction coefficient Three plastic extruders are used for simultaneous extrusion and compounding Widely used in optical cable communication network systems Features The silicon core layer on the inner wall is a solid permanent lubricant The silicon core layer on the inner wall is simultaneously squeezed into the highdensity polyethylene pipe wall and is evenly distributed across the inner wall of the pipe without peeling or detaching and has the same life span as the silicon pipe The silicon core layer on the inner wall has the same physical and mechanical properties as the highdensity polyethylene The friction characteristic of the inner silicon core layer remains unchanged and the cable can be drawn repeatedly in the pipeline The silicon core layer on the inner wall does not react with water and water can be used to flush the pipeline after an accident
