2、tute of Qilu Branch Co. , SINOPEC , Zibo, Shandong, 255400 )Abstract: The false fish eyes is the principal cause of PVC medical flexible tube surfacecssalient points, on the basis of performance comparison of two kinds of brands of PVC.According to contrasting the two kinds of brands of PVC resincs
3、basic performances, plastic-izer absorption time, internal structure and external form, the cause of false fish eyes werefound. The measures to decrease salient points during the processing were summerized.Key words : polyvinyl chloride; salient points; plasticizer; blend; medical flexible tube oY(
