Replacing synthetic binders

Penweave NW is a new naturally-derived binder for nonwovens being manufactured by Penford, a market leader in speciality starches and bioproducts headquartered in Centennial, Colorado.

The binder is compatible with all synthetic starches employed by the nonwovens industry and can replace between 30-60% in formulations, depending on the application. Penweave is equal in performance to latex binders, contains no volatile organic compounds and can significantly lower operating costs, the company says.

The PenWeave NW range includes both liquid and dry products, in addition to several different viscosity levels.

PenWeave NW 9320 is a ready-to-use liquid that can be added directly to the binder formulation with minimal time required for mixing.

Powedr variants can be hydrated in warm water with sufficient agitation or mixed directly with the binder, allowing the moisture in the mixture to hydrate them.
