WineCore

WineCore

WineCore (WGS) are technological biofillers obtained from grape seed processing by-products. These residues are generated by Tampieri Vegetable Oil in Faenza, representing a concrete example of a zero-kilometer supply chain.
The lignocellulosic composition, rich in tannins and fibers, gives WineCore ideal mechanical and functional properties for various industrial applications.
The biofiller is available in multiple grades to meet every application requirement.

Available Grades

Biofillers composed of quasi-spherical particles and microfibers. Ideal for injection molding, where fiber orientation can enhance the mechanical stiffness of the material.

Grade Umidity (% p.p.) d₁₀ [µm] d₅₀ [µm] d₉₀ [µm] Morphology Color
WGS B1 < 3% 16 ± 2 110 ± 20 360 ± 30 Near-spherical particles + microfibers Purple / Brown
WGS B2 < 3% 7 ± 2 50 ± 10 165 ± 20 Near-spherical particles + microfibers Purple / Brown
Note: Numerous other grades are available in our catalog, and custom grades can be produced upon request.

Biofillers featuring coarser particle sizes and microfibers, ideal when a visible biofiller presence is desired in the finished product or when dust reduction is required.

Grade Size Range Morphology Umidity
WGS GS30-10 1,0 – 3,0 mm Very coarse sand + fibers 10 – 14%
WGS GS15-3 0,3 – 1,5 mm Medium sand + fibers 10 – 14%
WGS GV3 < 0,3 mm Fine sand 10 – 14%
Note: Additional grades are available in our catalog. Upon request, we can also develop custom grades with tailored particle size distributions to meet specific application requirements.

Chemically optimized grades tailored for specific applications: enhanced hydrophobicity, dispensability, flowability, and mechanical response..

Grade Traetment / Improved Properties
WGS A201 Superior flow and improved ductility
WGS A301 Superior flow and improved dispersibility
Note: Additional grades are available in our catalog. Upon request, we can also develop custom grades with tailored chemical properties based on specific needs.
