FLEX/FOAM EXPANSION JOINT is an extruded closed cell plastic joint filler compounded from low density expanded polyethylene plastic foam. Resistant to chemicals and solvents, it has recovery properties of over 99%. Because of its cell make-up, it will absorb almost no water. FLEX/FOAM is chemically inert with no food value to attract or support plant or animal life.
