Flexible Form Liners
Polytek polyurethane mold rubbers are known for their durability when repeatedly casting concrete. Poly 74 and 75-Series systems are used extensively for casting decorative concrete panels, wall blocks, fencing, retaining walls, and more.
Use polyurethane liquid mold rubbers to create custom flexible rubber inserts or form liners that are placed into a rigid form. Liners can be easily removed from the form for demolding or replaced when a change in texture is desired. Polytek polyurethane rubbers can meet the demands of any size liner.
