Abstract:
Provided is a flooding composition. The flooding composition includes in weight percent (wt %) based on the weight of the composition: (A) from 1 wt % to less than 5 wt % of a polytetrafluoroethylene (PTFE) powder; (B) a styrene-ethylene/propylene block copolymer; and (C) a mineral oil having a kinematic viscosity from 32 cSt to 100 cSt at 40° C. Also a fiber optic cable is provided. The fiber optic cable includes a buffer tube; at least one optical fiber in the buffer tube; and the flooding composition.
