HTM 1440 B is an antiblocking masterbatch in a polypropylene copolymer carrier, which contains synthetic silica specifically selected because of its physical properties. Its great dispersion into the masterbatch provides the final product with superb 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 a formidable dispersion.
Minimal effect on the optical properties because of the silica’s refraction index is comparable to the polyolefin’s one.
Using HTM 1440 B does not impair the mechanical properties, leading to smother films also featuring a good resistance to scratching.
Adding HTM 1440 B makes easier the film unwinding and its further processing.
