HTM 1420 B is an antiblocking masterbatch in a polypropylene carrier, which contains synthetic silica specifically picked out because of its physical characteristics. Its high dispersion degree into the masterbatch provides the final product with excellent homogeneity. It is approved for food contact applications by both FDA and EU.
The optimal balance between the pore volume and the surface area of the added synthetic silica ensures an exceptional dispersion.
Minimal effect on the optical properties because of the silica’s refraction index is close to the polyolefin’s one.
Making use of HTM 1420 B does not impair the mechanical properties, getting smother films also featuring a good resistance to scratching
Adding HTM 1420 B eases the film unwinding and its further processing.
