"Although most of the processes used for the manufacture of polymer foams are well established, many producers have had to carry out development work over the last few years to adapt to new blowing agents which meet the requirements of the Montreal Protocol. This agreement has had repercussions worldwide and will continue to influence technical development for some time to come as the producers fine-tune formulations to try to match or exceed the material and process advantages provided by the original CFC blowing agents. Many of the applications for foam products have also been established for."@en . . . . . . . . . . "Electronic books"@en . . . . "Polymer Foams : Trends in Use and Technology" . .
