HTM 4420 T is a masterbatch that contains a high concentration of high-effectiveness additives, stabilized in a polypropylene carrier which sparks an immediate long-lasting antistatic effect. It is approved by the FDA to be used in plastic materials intended to be in contact with foodstuff.
The combination of additives which are found in HTM 4420 T gives the film both excellent surface resistivity and dissipation of the electrostatic charge.
The antistatic effect reaches immediately its optimal level thanks to the fast migration rate of the additives.
Adding HTM 4420 T has a minimal effect on the final product optical properties.
As a side effect, it is worth highlighting the good COF evolution provided by this masterbatch.
