Material Durability

  • Control of the service life through additives (prodegradants/stabilisers)
  • Gaining knowledge on the ageing behaviour of polyurethane foams, their use in plastic jacket pipes, determination of service life, prediction of service life and the associated clarification of ageing mechanisms
  • Development of test procedures
  • Investigation of methods for accelerated ageing


  • UV protection through nano-additives
  • Degradation accelerator
  • Plastic jacket pipe: long-term behaviour of polyurethane foams; amendment of EN253
  • Plastic jacket pipe: Method development for condition assessment
