Knapp’s Blue Series pigs use the same basic K-Lite foam system as the well-known Red Series. With Knapp’s unique ability to blend our own foam sytems, we alter the formulation of the urethane foam to make it softer, lighter (5 to 6 lb/ft3) and more flexible. The coating used for the Blue Series is also softer and more flexible than that found on the Red Series. The same coating patterns and scraper elements are available for the Blue Series.
