● Application
- TOWREX AF450 is a concentrate containing a highly effective blend of antifogging agents for PP films and wide food contact approvals.
TOWREX AF450 is incorporated into the polymer matrix during the extrusion process.
Upon extrusion the additive migrates to the surface of the polymer where AF450 is increasing the surface tension of the polymer.
A small quantity of the AF450 dissolves in the water droplet and decreases the surface tension of water.
At one point the surface tension of the polymer and the surface tension of the water are equal so that the water droplet is spread into a continuous layer of water, which is not wisible anymore.
● Dosage
▶ AF450 is recommended to add at a concentration of 0.5 ~ 1.0% into core layer in 3-layer BOPP films.
● Packing
▶ AF450S : 20KG Box
▶ AF450L : 18KG plastic bottle
