Abstract

Способ получения изоляционной прокладки охлаждения, включающий формование многослойного полимерного листа, включающего по меньшей мере один слой пены и по меньшей мере один твердый слой, расположенный рядом со слоем пены, придание многослойному полимерному листу формы прокладки, где прокладка является изолятором, где слои листа прикреплены друг к другу посредством экструзии расплава и где прокладка противостоит деструкции в случае контакта с хладагентом. Способ получения прокладки холодильного устройства, включающий совместное экструдирование вспененного слоя полистирола между двумя твердыми слоями высокопрочного полистирола для формования листа, термоформование листа в прокладку и включение прокладки в холодильное устройство. Способ формования многослойного полимерного листа, включающий плавление первой стирольной полимерной композиции, плавление и вспенивание второй стирольной полимерной композиции и совместное экструдирование первой и второй стирольных полимерных композиций для формования многослойного полимерного листа.
