Identification and assessment of alternatives to selected phthalates
Annex 3 Summary of technical performance parameters
A summary of some technical performance parameters for the assessed alternatives compared to DEHP, DBP, BBP and other selected phthalates is given below..
Technical key parameters of some plasticisers' performance in PVC (from Sears and Darby, 1982; Monsanto research work; unless noted)

Notes: *1: phr = parts per hard resin, meaning parts per weight of hard PVC. *2: A measure for the plasticiser's efficiency in making PVC flexible; the lower the number, the softer the PVC and the more efficient plasticiser. *3 Measured performance in another PVC resin (the same for DEHP and EHT). *4 Data from Danisco; at concentration 40 phr; PVC resin type not specified.
