Overview

Cymat Stabilized Aluminum Foam (SAF) is an innovative material with a combination of characteristics that can be engineered to provide solutions to the challenges facing automakers today. Particularly, Cymat SAF is a cost effective solution to address automotive companies' competing needs to lighten vehicles, yet improve crashworthiness and occupant protection. SAF is a lightweight material whose cellular structure provides superior energy absorption capabilities. These characteristics are becoming increasingly important as consumer demand and legislation require safer, more efficient, and easier to repair vehicles.

Lightweight

  • Can be used on its own, as part of sandwich panel or a plastic composite

Crashworthiness

  • Collapses at relatively constant load over large displacements - ideal for absorbing energy
  • Non-directional - will absorb energy, regardless of direction
  • Does not release poisonous substances at high temperatures

Semi-Structural

  • In tubular extrusions - foam stabilizes structure & delays onset of failure, particularly in curved sections or sections experiencing bending loads
  • Optimizing tube wall thickness and foam density can minimize weight of structure

Consistent and Constant Material Properties

  • Constant properties over time, operating temperature and moisture range
  • Properties do not vary with speed of loading

Noise and Vibration Harshness

  •  Good sound absorbing capabilities
  •  Restricts sound transmission by up to 90%

Thermal Insulation

  •  Non-combustible as set out in ASTM E136-92
  •  Insulation R-values of 20-30

Environmental Impact

  • 100% recyclable
