The EVA plastic film for V-process and steel castings by V-process in China

EVA plastic fi lm is the key material for V-process. Through decades of research, special EVA fi lm for V-process has been produced. The fi lm has adequate elongation; its maximum is about 800% in longitudinal direction and 750% in transversal direction. The single width of the fi lm is 2.8 m and the double width is 5.6 m, which is the widest sheet fi lm for V-process in China. Sheets with different thickness ranging from the thickest 0.35 mm to the thinnest 0.08 mm can meet different demands in China. The fi lm can be used not only for V-process of iron castings, but also for the manganese steel railway frog, steel rocking support and side frame castings for train and the steel bridge box for engine truck.
