Durethane M

• Microcellular foam
• Mechanically mixed
• Self-cleaning, non-glazing
• Uniform cell size
• Excellent compression set properties
• Physical properties consistent with light duty applications
• Available with integral skin
  
  
  
  The printing pad in this postage meter will last up to 15 million cycles. Made from Durethane M, the extremely uniform cell size of the material provides the compression set resistance needed to withstand repeated compression cycles. In addition to printing pads, typical uses include idler belts and low volume feed roller applications.

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