Application Areas

Joint seals: AEP blends and formulations can be used to modify elastomers and sealants so that they swell on absorption of water. This action assists the seals to self-heal against the passage of water.

Features of AEP Compounds
  • Biologically benign
  • Cross linked for chemical stability
  • Variable formulations for tailored properties
  • Wide choice of expansion volumes
  • Wide choice of expansion rates
  • Stable and consistent from pH 1 to pH 14 inclusive
  • Stable and consistent in distilled water and saline to 20+% NaCl
  • High temperature stability to 180+ deg C

AEP materials and formulations can be used in combination with a range of sealnts and elastomers to form water-swellable gaskets and jointing materials. These materials can be used to form self-healing seals.
