The Silicon HDPE Duct is a new type of composite pipe with a silicone solid lubricant on the inner wall. Simultaneous extrusion and compounding by two plastic extruders, the main raw material is high-density polyethylene, and the core layer is a solid lubricant silica gel with the lowest friction coefficient. Therefore, the silicon core tube has many characteristics unmatched by other products in terms of physical properties, service life, comprehensive cost, and optical fiber cable construction.
