Retimet Replacement Foam

Matching Retimet® Properties with Duocel®

  • Retimet is sold in a variety of “grades”, while Duocel is sold by “pore size” measured in Pores Per Inch (PPI)
  • Grades loosely translate to PPI. (i.e. 20NC has roughly the same pore size as Duocel 20 PPI aluminum foam.
  • High density Duocel foam provides very similar flow rates to the same pore size Retimet foam.
  • Duocel is produced at up to 40 PPI, but is compressible while maintaining uniformity thanks to our solid ligaments.  Higher grades of Retimet may be replaced by compressing Duocel foam.
  • Standard aluminum Duocel® can meets properties of Retimet® grades 45NC, 60NC and 80NC
  • Nickel-Plating Duocel® aluminum foam often closes the gap on yield strength for 10, 20 and 30 PPI foams
  • For all grades/pore sizes, Nickel plating may not be needed if yield strength is not a critical requirement

 

 

Advantages of Duocel®

  • Solid ligaments provide strength and heat transfer.  
  • Brazing and bonding compatibility for exceptional thermal interfaces
  • Highly customizable for all modes of heat transfer, crush performance, and more!
  • Tunable for a wide range of properties
  • Decades of design and testing data
  • Enviromentaly friendly!

Duocel®

  •  Maximize Surface Area to Volume Ratio with pore size and compression

Retimet Alternative Projects

  • Liquid Flow Control
  • Diffusors
  • Air/Oil Separators (see below)
  • Flame Arrestors
  • Sound Absorption

By matching density and pressure drop, Air/oil Separators are a common example where Duocel can be a certifiable replacement for Retimet
