ALKAMIX™ MB-AO300 is BHT (Butylated Hydroxy Toluene) free antioxidant masterbatch designed to impart thermal processing stability to base grade low density polyethylene during extrusion.

ALKAMIX™ MB-AO300 can be added to base grade low density polyethylene during extrusion to assist in overcoming thermal instability problems. The level required will vary according to the type of extrusion, conditions and polymer used, however the recommended addition level is between 1 and 2 percent.

ALKAMIX™ MB-AO300 can also be used as a shutdown compound to prevent oxidation of polymer left idle in an extruder. As a shutdown compound, it is usually added at concentrations of 30 percent or more to fractional MFI low density polyethylenes.
