CornCore

CornCore

CornCore (GTF) line biofillers are high-performance technical biofillers produced from corn germ meal, a natural by-product of corn germ processing at Tampieri Vegetable Oil. Its lignocellulosic composition—rich in starch and proteins—gives CornCore exceptional dispersibility and processing versatility. Available in multiple grades including B (micronized), Sand & Fiber, and Advanced, it seamlessly adapts to a wide range of industrial sectors.
