Polytek® two-part, room temperature curing mold rubbers are used to create custom flexible rubber inserts or form liners that are placed into a rigid form. These highly detailed liners are often used to cast decorative concrete panels, wall blocks, fencing, retaining walls and sound barriers. 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.
