Chemical Name     1:1 –Combination of Phosphonic acid, [[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]methyl]-, monoethylester, calcium salt (2:1) and polyethylene-wax

CAS No.           Preparation

Structure          Antioxidant 1425

Molecular Weight (Antioxidant 1425): 695

Applications

Antioxidant 1425 WL is particularly well suited for polypropylene fibers, when combined with Sanox 168.

FEATURES/BENEFITS

Antioxidant 1425 WL in combination with Antioxidant 168 gives good processing stability during polypropylene fiber production. It shows good gas fading resistance and low color development during storage. Antioxidant 1425 WL 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.
