Features of time characteristics of diffusion properties of polymer modified film materials for technical application

Abstract: Особливості часових характеристик дифузійних властивостей полімерних модифікованих плівкових матеріалів технічного застосування Львівський торговельно-економічний університет, 79008, Україна, Львів, вул. Туган-Барановського, 10, е-mail: nina.domantzevich@gmail.com; bogdan.yatsyshyn7@gmail.com Досліджено зміни киснепроникності упаковок із полімерних плівкових матеріалів, призначених для тривалого зберігання металевих виробів. Зафіксовано високі показники початкової киснепроникності з-за ненадійних ізоляційн… Show more

“…Such growth of polyethylene crystals is more characteristic with the aging of matrices enriched with crystallization accelerators, in the form of gas corrosion inhibitors of metals which injected for a specific purpose into the polymer [2]. In inhibited polymer coatings, such processes, as a rule, proceed early as 3 -4 years, achieving a significant development of crystallization processes, which turn into degradation at 5 -6 years [3]. Such development of structure formation processes is quite unexpected, since the formation of the structure in samples with organic filler is more consistent to films with plasticizer additives, which due to the increased amorphousness results have less surface defect [4].…”
