Use advice for data set
The data set can be used for all LCA/CF studies where the product is needed. Combination with individual unit processes using this commodity enables the generation of user-specific (product) LCAs. Due to high resistance to light and thermal aging, as well as thermal stability of polyurethane produced with APPs, the polyurethane/polyisocyanurate (PUR/PIR, in the following the common term for both PU is applied) products are used for paints, coating materials and flame-retarded rigid foams [ULLMANN 2010]. They also may be formulated into adhesives, sealants, and elastomers. Polyurethanes are made from polyols e.g. APPs and polyisocyanates. Typical isocyanates used include polymeric methylene diphenyl diisocyanate (PMDI) in rigid foam applications. Toluene diisocyanate (TDI) is used in flexible foam applications. Monomeric MDI is used in adhesive, coating, sealant, and elastomer applications. Flame retardants may be included in the APP batch and/or added separately during PUR production. This Eco-profile refers to APP without flame retardant additions. When used in thermal insulation products, the use phase results in substantial energy savings of buildings / technical installations / fridges over their use phase. Today’s most important process for an end-of-life is an energy recovery of the PU material.
Data set use approval
General comment
The main data source was a data collection from European producers of APP. Primary data on gate-to-gate APP production is derived from site-specific information for processes under operational control supplied by the participating companies of this Eco-profile: five APP producers with six plants in five different European countries. This covers more than 75-85 % of the European APP production (EU-27) in 2020. Land use cannot be read out correctly as the areas were not collected for the foreground system.

Technical purpose
Polyester Polyols are important intermediate products for many production chains. APPs are used to manufacture polyisocyanurate (PIR) and polyurethane (PUR) rigid insulation foam, which finds extensive use in the automotive, construction, refrigeration and other industrial sectors. Other uses include flexible polyure-thane foams, semi-rigid foams, and polyurethane coatings. A major part of the world’s polyols production is shared by two groups of polyols, namely polyether and polyester polyols.
