The Unique Properties of Polyurethane Foam for Small Engine Filters

The properties of reticulated polyurethane foam have been investigated to determine its suitability as a small engine filter system. Polyurethane foam is useful in small engine filter systems due to the ease of manufacturing, freedom in geometric design, variable physical properties, and ease of property modification and filter enhancement through the use of composite materials and coatings.

The results of this study will give direction to the filtration designer to optimize the selection of the proper polyurethane foam or foam combinations along with the geometric configuration to obtain a suitable design.
