Chiguard® 234 is most suitable for polymer production where additive losses may occur during high temperature processing. Therefore, Chiguard® 234 has been widely used in the following area:
- PET fiber and film
- PC
- POM
- Nylon
- TPE compounding
A percentage of 0.1% - 0.5% of Chiguard® 234 is recommended for protection. Light stability of polymer can be further enhanced by use of a phenolic antioxidant (e.g. DEOX 10 and 76) and a hindered amine light stabilizer (e.g. Chiguard® 770 and 944) in the combination with Chiguard® 234.
