Viochem Antioxidant 245

Ethylenebis(oxyethlene)bis-(3-(5-ter-butyl-4-hydroxy-mtolyl)-propionate). Acts as an antioxidant. Is effective in styrene polymers, particularly impact modified polystyrenes, ABS, MBS, SB and SBR-lattices as well as in POM homo-and copolymers. It is also very useful for the stabilization of polyurethanes, polyamides, thermoplastic polyesters, PVC and other polymers. In addition to imparting thermostability to the finished polymer, it is effective as chain stopper during PVC polymerization. Can be used in combination with other additives such as costabilizers (e.g. thioesters, phosphates, phosphonites, lactones), light stabilizers, and other functional stabilizers.
