Highly flexible; excellent environmental properties -60° to 275°F (-50° to 190°C)

MAGRAM UDMAGRAM UD combines superior energy absorption properties of high performance magnetic materials with the desirable physical properties of urethane. The flexible, loaded urethane rubber based microwave absorber can be tuned for mode suppression in an enclosed cavity, signal isolation and surface current attenuation.

Product Overview
MAGRAM UD is mechanically stable, and resistant to extreme environments and temperatures, it has good tensile strength, elongation, tear strength and compression set that can be far superior to conventional rubbers. This product is halogen free, RoHS and REACH compliant. Attenuates: from 500 MHz to 40GHz

urethane binderWhy MAGRAM UD is effective
The urethane binder is used in a high abrasion environment taking advantage of its tear strength and UL 94-HB rating. This binder in combination with the various fillers makes it effective for absorption.

When to Use 
MAGRAM UD is most effectively used where the urethane material properties can be taken advantage of, especially environmental issues. With any of the MAGRAM series the fillers can be combined with various binders.

  • Specular Return (RCS, aircraft exteriors, etc)
  • Surface Current Reduction
  • System Isolation (antenna, circuit component)
