The general purpose of the PUrePAIR project was to develop new and improved polyurethane foams and elastomers with self-healing properties. The self-healing capacity was to be obtained by adding microcapsules with a newly developed chemistry as healing agent.

Following objectives were envisaged:

• Development of new microcapsules to incorporate various chemistries and development of a continuous production process for the capsules
• Development of a new route for the self-healing concept
• Evaluation on processing of incorporating self-healing microcapsules in PU foams and elastomers
• Proof-of-concept of self-healing in a PU matrix
