Stabilizers ba sau ɗaya kawai suke aiki ba - suna kare fim ɗinku ta kowane mataki, daga layin extrusion zuwa shiryayye. Ga yadda:
1.Matsayin samarwa: Ci gaba da Gudun Layukan (da Rage Sharar gida)
Mafi girman farashi a masana'antar fim mai raguwa shine lokacin hutu. Stabilizers tare da ginannun man shafawa suna rage juzu'i tsakanin narke PVC da extrusion ya mutu, yana hana "gelling" (gurjin da ke toshe inji).
