Insulation manufacturer. Munn & Steel MICAFIL INSULATION.
Type: Loose fill.
Manufactured in Manitoba from what I reviewed but will look further.

Here is an image of the packaging.
Robert, you may want to correct your thread title from" Mocafil insulation" to “MICAFIL insulation” in the event someone is doing a search for the insulation in the future…
Just a thought…
