hey
Explanation: 

The fluorine is more electronegaative than sulfur .The bond applies dipoles therefore point towards fluorine .The six S-F bonds arranged in an octahedral fashion around the central sulfur :

But the as per VSEPR theory the six fluorine atoms are arragned in symmetrical octohadral geometry around the central sulfur atom which leads to the cancellation of the bond dipoles and the molecule in non polar

Answer: 

SF6 is non polar
