Polymer foaming (polymer foaming)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. This is delivering the service of 'polymer foaming'. Foams are generated by adding physical (gases and low-boiling compounds) or chemical blowing agents (gas-releasing compounds) to the polymer. In principle all polymers can be foamed but only a limited number of materials have been employed in the manufacture of foams such as the thermoplastics polystyrene poly(vinyl chloride) and low-density polyethylene (LDPE) as well as phenolic and polyurethane resins. In the service of foaming 1 kg of input corresponds to 1 kg of expanded plastics. The converted amount of plastics is not included into the dataset. Thus it should be used along 1 kg of plastic that can be foamed(usually polystyrene). The cut-off classification is allocatable product. The activity type is ordinary transforming activity. The reference product amount is 1.
