Sillitin Z 89 offers good light scatter and IR barrier as well as low optical turbidity.
- very low residue
- good dispersion properties
- good anti-blocking properties
- light-scattering properties adjustable per product type
- high light transmission in the photosynthetically acitve range (400 to 700 nm)
- high infrared barrier, particularly in the terrestrial radiation range (7 to 143 µm)
