Applications YINOX 1425 is particularly well suited for polypropylene fibers, when combined with YINOX 168.
Features/benefits YINOX 1425 in combination with YINOX 168 (IRGANOX B 501 W) gives good processing stability during polypropylene fiber production. It shows good gas fading resistance and low color development during storage. YINOX 1425 performance is practically not influenced by alkaline additives (e.g. spin finishes, HALS, antacids). It makes PP fibers brilliant, which is of particular interest in some BCF/CF applications. Its long-term thermal performance is unmatched by any other phenolic in the market.
