IRGANOX 245
IRGANOX 245
Irganox® 245 is a phenolic primary antioxidant for processing and long term thermal stabilization.
Applications for IRGANOX 245
Irganox® 245 is a sterically hindered phenolic antioxidant that protects organic substrates against thermo-oxidative degradation during manufacturing, processing, and end use.
This antioxidant is effective in styrene polymers, particularly impact-modified polystyrenes, ABS, MBS, SB, and SBR-latices, as well as in POM homo- and co-polymers. It is also very useful for the stabilization of polyurethanes, polyamides, thermoplastic polyesters, PVC, and other polymers. In addition to imparting thermostability to the finished polymer, it is effective as a chain stopper during PVC polymerization.
This product can be used in combination with other additives such as co-stabilizers (e.g. thioesters, phosphites, phosphonites), light stabilizers, and other functional stabilizers. The effectiveness of Irganox® 245 with Irgafos® 168 is particularly noteworthy.
IRGANOX 245 is recommended for applications such as:
- Sealants
- Solvent-based coatings
- Hot-melt adhesives
Features & Benefits
- High extraction resistance
- Low volatility
- Odorless
- Good color stability
