phenolic antioxidant
Yinox® 235 125643-61-0 Colorless to slightly yellow liquid

Yinox® 235 is an excellent liquid antioxidant can be used in a variety of polymers. For the stabilization of polyurethane flexible slabstock foam, it prevents the formation of peroxides in the polyol during storage, transport and further protects against scorching during foaming.

Yinox® 525 88-58-4 White crystalline powder

Yinox® 525 is generally used as a polymerization inhibitor, an antioxidant and a stabilizer. It is used mostly in industrial applications, particularly in rubbers, coating, adhesive and adhesive films, paints and monomers.

Yinox® 920 110553-27-0 Pale yellow liquid

Yinox® 920 is an effective thermo-oxidative stabilizer in thermoplastic elastomers including BR,SBR,NBR,IR,SBS and SIS as well as natural rubber.

Yinox® 333 732-26-3 White crystalline powder

Yinox® 333 is a pollution-free hindered phenolic antioxidant for plastic, rubber, coating, resins & adhesive. With the lower volatility and better thermal stability, it can be used instead of BHT.

Yinox® 446 90-66-4 White powder

A hindered thiophenol antioxidant especially for XLPE or HDPE wire & cable compound. It has high resistance to thermo-oxidative degradation and wash-out, exhibits excellent compatibility with peroxides and exhibits great synergism with carbon-black.

Yinox® 430 96-69-5 White crystalline powder

A hindered thiophenol antioxidant especially for XLPE wire & cable compoundor HDPE/LDPE water & gas pipes. It is also used as a polymerization and processing stabilizer for PP, ABS,PVC,EPDM elastomers and polybutadienes.

phosphite antioxidant
Yiphos® 3035 —— Clear or light yellow sticky liquid

Yiphos® 3035 has outstanding color improvement & long-term stability. It also reacts as light stabilizer with excellent photostability due to its special hindered amine structure. It is widely used in all kinds of applications including PVC, Polyether polyol, Epoxy resins, Unsaturated resins, Polyurethane etc.

Yiphos® 2105 80584-85-6 Clear liquid

Yiphos® 2105 is a diphosphite antioxidant specially for polyurethane & PVC products.

Yiphos® 2020 4712-55-4 Clear liquid

Yiphos® 2020 is an excellent catalyst for esterification & a non-stain, non-discoloration stabilizer for elastomers, adhesives, engineering plastics, synthetic resins.

Yiphos® 3032 —— Clear colorless liquid

Yiphos® 3032 is widely used in all kinds of applications. The heat stability is superior when at 1/3 dosage of TPP because of the higher active phosphorus content, consequently it can replace the traditional phosphite antioxidants.

Yiphos® 3012 —— Clear colorless liquid
Yiphos® 3010 26544-27-4 White turbid liquid(Normal temp.)/Clear liquid(≥100℃)

Yiphos® 3010 is a phosphite antioxidant which can be used in the high molecular material such as lubricants, polyurethane, resins, polyester polyols and coating etc. Synergism is realized when it is combined with hindered phenols and UV absorbers.

Yiphos® 2103 80584-86-7 Clear liquid

An effective liquid phosphite antioxidant for many types of polymers including PVC, ABS, Polyurethanes, Polycarbonates and coatings to provide improved color and heat stability during processing and in the end application.
