Flexible PVC stabilizers have low phenol, phosphite. (Additives).
Moreover, this stabilizer is also said to have better synergy with uv absorbers such as benzotriazoles, which can interact with phenolics and cause yellowing. In clear wire coating, it is said to maintain excellent resistance to copper greening.
New Mark 4853 Ba-Zn is one of a new generation of stabilizers for general-purpose molding, extrusion, and calendering that have very low VOCs. It is aimed at indoor applications like wall coverings. Its low phosphite content reduces phenol emissions during processing. The company is also developing Ca-Zn stabilizers with reduced phosphite levels. All these products have higher metal content to make up for the reduction in phosphite. Tel: (203) 573-2000, www.cromptoncorp.com
