çevı rı cimce % 5'den daha fazla su emmemeve 500 - 700 donma-çözünmedöngüsüdür. Bu test aynı zamanda su buharının geçişini zorlamak için ısı ve konsantrasyon farkı yaratılarak, su emme miktarının incelendiği laboratuvar test sonuçlarıyla desteklenerek incelenmelidir. TEŞEKKÜR Yazıdaki uzman/cır bu bilgilerin derlenmesinden sorumlu olmakla beraber, bu veriler Horgen, Switzerland, Samia, Canada ve Midland, Michigan gibi Dow lokasyonlarındaki birçok kişinin çabası ve işbirliği vasıtasıyla meydana getirilmiştir.
