SF6 is non-polar.
Reason:
Fluorine is more electronegative than sulfur, so the bond dipoles point toward fluorine. However, all the six S-F bonds are arranged octahedrally around the central sulfur. F F

F-S-F

F F Because the octahedral geometry is symmetrical, the bond dipoles cancel each other, and the molecule is nonpolar, meaning that µ = 0. Source: Another Qs from the same topic (SF6 from wikiANSWERS) which quotes the source as:

SF6 is unreactive towards water because it is a non-polar molecule with strong covalent bonds, making it difficult for water molecules to break these bonds. TeF6, on the other hand, is reactive with water because it contains a metal (tellurium) and highly electronegative fluorine atoms, resulting in a more polar molecule that can easily react with water to form products.
A polar molecule.
Water IS a polar molecule.
O2 is non polar molecule .
H2O is a water molecule, which is polar.
The neutral SF6 molecule has no dipole moment. The gas phase SF6- ion is not that well understood- on the basis that the shape is distorted octahedral a small dipole would be expected.
A molecule with polar bonds can be overall non-polar if the bond dipoles cancel each other out. For example the following all have polar bonds but the bond dipoles cancel each other out (vector addition) to make the molecule non-polar. Linear - CO2 trigonal planar - BF3 tetrahedral molecules, CF4 trigonal bipyramidal PF5 octahedral SF6

No a molecule is a molecule, polar or nonpolar.

SF6 is a covalent compound. It consists of nonmetals, sulfur, and fluorine, which share electrons to form covalent bonds within the molecule.
