DIAB Klegecell® R 260 Rigid, Closed Cell PVC Foam Core Material (discontinued **)
Categories:	Other Engineering Material; Composite Core Material; Polymer; Thermoplastic; Vinyl (PVC); PVC, Foam Grade
Material Notes:	Klegecell R is a PVC based, rigid, closed-cell foam with a tri-dimensional grid structure, which provides high thermal stability and structural integrity. As a structural core, Klegecell R is used in conjunction with high strength facings to produce lightweight, yet exceptionally stiff composite structures. Klegecell is widely used and found in pleasure crafts, tanks, high performance boats, vehicles, and many other high-strength, low-weight applications. Information provided by DIAB, Inc.
