Can i use this to insulate hvac metal duct?

Yes, but why when regular fiberglass in much cheaper? This product in intended for temperature much higher than any HVAC requires. You may want to use this for an exhaust from a furnace flue to insulate the high temps (in excess of 200 degrees F.) from other parts of the furnace or structural components of a building.

Would this be effective using as acoustic insulation?

No, it is solely for insulation around a wood stove insert.
