SiO2 forms a covalent network, and is not molecular. Silicon dioxide does not form individual molecules, and there are no double bonds. Silicon dioxide forms a tetrahedral network of silicon atoms bonded to 4 oxygen atoms so as a whole (if there were 4 Si-O bonds), then the system as a whole would be non polar.

SiO2 is Polar because the dipole moments do not cancel each other. If the dipole momements cancel it is non-polar.
