GTF Biofiller

from corn

The GTF biofiller is our technological biofiller obtained from the corn germ meal by-products.
These residues are generated by Tampieri spa in Faenza, thus representing a true example of zero kilometers.
The GTF biofiller can be supplied in different grades:

GTF B grades
GTF Advanced grades
GTF Sand&Fiber grades
GTF Master grades

GTF B grades

The GTF B grades are our most versatile grades which can be successfully used in many applications thank to their low and controlled particle size distribution and to their controlled moisture values.

GTF Advantaged grades

The GTF Advanced grades are our customized biofillers for specific needs. We can improve many properties such as hydrophobicity, dosability and flowability, and mechanical response.

GTF Sand&Fiber grades

The GTF Sand&Fiber grades are our biofillers composed of coarser particles and fibers, to be used when a visible presence of the biofiller in the finished product is desidered or for applications in which dustiness needs to be avoided.

GTF Master grades

GTF biofillers can be concentrated (up to 50-60%) into masterbatches using polyolefinic or biodegradable resins as carriers to facilitate their use for plastic applications.
