Silicon core pipe is a new type of composite pipe with silica gel solid lubrication system on the inner wall, which is widely used in optical cable communication network systems such as highways and railways. HDPE silicon core pipe is a new type of composite pipe with silica gel solid lubrication system on the inner wall, which is called silicon pipe for short. Three plastic extruders are simultaneously extruded and compounded. The main raw material is high-density polyethylene, and the core layer is silica gel, a solid lubricant with the lowest friction coefficient. Widely used in optical cable communication network system. The following factors should be considered when selecting master batch: 1. Friction coefficient: static less than 0.25 and dynamic less than 0.15 can meet the requirements of crosstalk. 2. Compatibility: the masterbatch carrier is matched with HDPE, otherwise delamination will occur. 3. The cover of color masterbatch must be good. 4. The dispersity of color masterbatch meets the use requirements of HDPE raw materials. 5. Silicone adopts high molecular weight design masterbatch.
