The purpose of wadding is to protect the parachute from the heat of the ejection charge. This is a type of cloth wadding that does not need to be replaced between flights. It saves money, especially on large diameter rockets that would need a lot of regular disposable wadding to protect the chute.
People also ask, what can I use for rocket wadding?
By far the most commonly used alternative to recovery wadding is cellulose insulation. Cellulose is made from recycled paper and is treated with boric acid to be fire resistant. Boric acid is a natural substance, but it is also poisonous.
Secondly, what does recovery wadding do? Recovery wadding is necessary to protect your parachute from being damaged. As your rocket’s motor burns out, it emits a small “burst” or “charge” that pops the nose cone out, and deploys the parachute. Without the wadding, the chute could be burned.

How do you make paper fire retardant?
The treatment couldn’t be simpler: soak the paper in a saturated solution of borax (sodium tetraborate decahydrate) in water, then let it dry. Alum (potassium aluminum sulfate hydrate) is also commonly used for this purpose, but not quite as easy to find. Borax is available at most grocery stores.
