Cortec’s BioPad earns USDA-certified biobased content label


BioPad, a solution within Cortec corrosion product line, has been recognised as a US Department of Agriculture (USDA)-certified biobased product. The recognition will allow Cortec to display a USDA label on BioPad, highlighting its percentage of biobased content. This is the portion of a product that comes from a renewable source, such as plant, animal, marine, or forestry feedstocks.

In the case of BioPad, which contains 58% USDA-certified biobased content, this includes byproducts of corn processing. By utilising renewable, biobased materials, companies like Cortec are able to displace the need for non-renewable petroleum-based chemicals.

Kate Lewis, senior analyst for USDA BioPreferred Programme, commented: “Products from Cortec are contributing to an ever-expanding marketplace that adds value to renewable agriculture commodities, creates jobs in rural communities, and decreases our reliance on petroleum.”

BioPad is a flexible corrosion inhibiting device constructed from biobased non-woven material, providing a sustainable packaging option for corrosion inhibition. Its Vapour Phase Corrosion Inhibitors (VpCI) concentration, in combination with a thin design, results in material reduction by up to 94% in comparison to similar polyurethane foam emitting devices, Cortec claimed.

By placing the BioPad into packages will allow metal items be protected. VpCI infused throughout the non-woven substrate will vapourise and fill the enclosed package or space, forming a protective molecular layer on the metal surfaces.

BioPad complements to VpCI-126 Film where a high density of VpCI is required to saturate the inside of a package. It can be used as a standalone, or combined with other materials across several applications, including shipping and storage of auto parts, and in-process protection for crates or racks of gears.
