Dissolving Nylon PA6/PA66/PA610

Dissolving Nylon PA6/PA66/PA610

Dissolving Nylon PA6/PA66/PA610


I am in a Covid-related raw materials crunch at my company and I need to make a product that is similar to DuPont Elvamide 8063 Multipolymer; the multipolymer components for Elvamide being PA6 PA66 and PA610.

Currently, we take a 55.1 pound bag of Elvamide 8063, pour it into a 55 gallon drum and fill to the top with methanol. A little heat and agitation and it turns into liquid form.

What I need help with is how much formic acid to use if I were to pour 55.1 pounds of a combination of the aforementioned polymer group into a 55 gallon drum along with methanol to the top.

Does anyone know how much formic acid I need to add (along with anything else) to dissolve the nylon?

Thanks very much.

RE: Dissolving Nylon PA6/PA66/PA610

Formic acid is incredibly nasty and smelly. I doubt your EHS people will allow that much being used. Also, formic acid reacts with methanol to form an ester. I think you would need advice from a professional chemist before proceeding.
