Applications YINOX 330 is used in polyolefins e.g. polyethylene, polypropylene, polybutene for the stabilization of pipes, molded articles, wires and cables, dielectric films etc. Furthermore, it is applied in other polymers such as engineering plastics like linear polyesters, polyamides, and styrene homoand copolymers. It may also be used in PVC, polyurethanes, elastomers, adhesives, and other organic substrates.

Features/benefits YINOX 330 has good compatibility with most substrates, high resistance to extraction and is odorless. It offers also excellent dielectrical properties. The product can be used in combination with other additives such as costabilizers (e.g. thioethers, phosphites, phosphonites), light stabilizers and other functional stabilizers. The effectiveness of the blends of YINOX 330 with IRGAFOS 168 (IRGANOX B-blends) is particularly noteworthy. YINOX 330 is particularly recommended for polyolefin applications requiring good water extraction resistance combined with low color development. Furthermore, YINOX 330 reduces water carry-over in polypropylene tape
