Introduction:
Antioxidant 245 is a sterically hindered phenolic antioxidant particularly suitable for organic substrates. It protects the substrates against thermo-oxidative degradation during manufacturing, processing and end-use. And its special features involves high efficient antioxidantion, low volatility, resistance to oxidation coloring, significant synergistic effect with assistant antioxidant (such as monothioester and phosphite ester), and giving products good weathering resistance when used with light stabilizers. It is effective in styrene polymers, particularly impact modified polystyrenes, ABS, MBS, SB and SBR-latices as well as in POM homo- and copolymers. It is also very useful for the stabilization of polyurethanes, polyamides, thermoplastic polyesters, PVC and other polymers. While it also serves as end stopper of chain in PVC polymerization. In addition, the product has no effect on polymer reactions. When used for HIPS and PVC, it can be added into monomers before polymerization. The amount to be used may be 0.05%~0.5%.
Characterization:
IRGANOX 245 is a sterically hindered phenolic antioxidant particularly suitable for organic substrates. It protects the substrates against thermo-oxidative degradation during manufacturing, processing and end-use. IRGANOX 245 is odorless, of low volatility, has a good color stability and exhibits high extraction resistance.
Application:
* Primary antioxidant for organic polymers.
*High performance sterically hindered phenolic antioxidant that protects the polymeragainst thermo-oxidative degradation during the manufacturing processes andin end-use applications
*An effective antioxidant for styrenics, synthetic rubbers, POM homo &copolymer,polyurethanes, polyamides, polyesters, MBS and PVC.
* Low volatility, good color stability, and extraction resistant
* Chain Stopper in PVC and ABS manufacturing process
* Fish Eye reduction in flex-PVC applications
* Can be used with benzotriazoles or HALS for thermal and light stabilizationin outdoor use.
* Exhibits a synergistic effect when used in combination with thioester antioxidants.
