SFF B grades
The SFF B grades are our most versatile grades which can be successfully used in many applications. They are composed both by tiny particles and micro-fibers to simultaneously improve processability and mechanical response.
SFF Advantaged grades
The SFF Advanced grades are our customized biofillers for specific needs. We can improve many properties such as hydrophobicity, dosability and flowability, and mechanical response.
SFF Sand&Fiber grades
The SFF 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.
SFF Master grades
SFF biofillers can be concentrated (up to 50-60%) into masterbatches using polyolefinic or biodegradable resins as carriers to facilitate their use for plastic applications.
