Durethane F

• Cellular foam
• Chemically blown
• Self-cleaning, non-glazing
• Larger, less uniform cell structure
• Replicates performance of solid, with flexibility of foam
• Excellent shock absorption and resiliency
• High tear strength and tensile modulus
  
  
  
  The functions of the cellular foam pick pad, entrance guide and retard pad are similar in that they require uniform coefficients of friction and durability. Durethane F has low compression set and provides the self-cleaning characteristics of a microcellular foam in one unique material.

  The table represents typical ranges of physical properties for materials formulated from Durethane F. For information about custom formulation and the specific values attainable for your application, please call our sales department at +1 (401) 946-4400.
