Free Foaming

To give a competitive and ecologically valid answer to the increasing demand of foam polymer products (strong demand of insulation materials, lighter plastics, etc.), it is necessary to reconsider the foaming technology and the chemical agents that are being used.

The economically sound substitution of SVHC foaming agents is an urgent challenge for the plastics processing, textile, coating and other industrial sectors. Substitution not only means a switch from one foaming agent supplied by one producer to another (in as far as they are available for the diverse polymers), but also means the related process and product developments and possible adaptations to the machinery.

Approach of the "Free Foaming" project:

  • Screening and characterisation of foaming and nucleating agents that may be used in polymer foaming (thermosets, thermoplastics, composites, coatings)
  • In the case of textile coating: substitution of exothermic foaming agents by endothermic ones of combinations, for both plastisols (PVC) and dispersions (acrylate or polyurethane)
  • In the case of plastics: substitution of exothermic foaming agents by endothermic ones, evaluation of physical foaming, solid state pre-saturation, foam beads and micronized chemical foaming agents.
  • (Semi) industrial trials
  • Characterisation of the foam structures
