SEM analysis indicated that the dispersive state of nature rubber latex was improved with the addition of organosilicone. The two batch formulas were adopted in the manufacture of urethral catheter with an optimal addition of 1.5% of KGF-903. The catheters were obtained with smooth surface, finer evenness, moderate hardness and favorable yield of latex sacculus. The separation forces between connector and the interface of conical drainage as well as the tensile force between gas loading filler and drainage tube were improved, which guaranteed the safety of Foley latex in clinic use.
