Polywater® + Silicone™ types NN and NB are a family of high performance, specification grade, cable pulling lubricants that demonstrate superior performance in two areas: friction reduction on HDPE (polyethylene conduits) and PVC materials. These lubricants provide continuous lubrication when pulling through water and are suitable for all types of cable pulling. They are the industry preferred cable pulling lubricants for the longest pulls of heavy transmission cable and pulling cables in a wet environment. They are suitable for use with factory lubricated ducts. They continue to lubricate under high sidewall pressure forces in conduit bends. Both type NN and NB are slow drying and leave a thin, slippery film that retains its slip for months after installations. While they can be applied by hand, it is best to pour or pump the lubricant into the duct during cable pulls.
