First, product performance

Ciba 168 protects those polymers that are exposed to oxidizing atmospheres and avoids changes in the molecular weight (such as chain breaking and cross-linking) and the matrix during its processing (mixing, granulating, shaping, recycling applications) Color change. Ciba Antioxidant 168 and phenolic antioxidants when combined with the best results. These compounds can also be used with other complex stabilizers such as lactones and light stabilizers (UV absorbers, hindered ammonia, tinuvin and chimassorb products).
