SunCore

SunCore

SunCore (SFF) products are technological biofillers derived from sunflower seed meal, a by-product of the oil extraction process by Tampieri Vegetable Oil. Its lignocellulosic composition, rich in proteins and natural fibers, provides SunCore with good mechanical reinforcing properties. The presence of elongated plant fibers makes it particularly suitable for applications requiring an anisotropic reinforcement effect or a visible texture in the finished product.
