Hostanox™ O 3 powder
Hostanox O 3 powder is a highly efficient phenolic antioxidant with high resistance against hydrolysis, providing long term heat stabilization to polyolefins and polyamide especially for applications where the final article comes in contact with extractive media such as water, fat etc.
Product Information
- Exceptional resistance to extractive media and chlorinated water
- Excellent booster for OIT for pipes applications
- High color retention
- Powder coatings: Anti Oxidant with good hydrolysis resistance and prevent yellowing upon heat exposure

Hostanox O 3 powder is recommended for the stabilization of polyolefins (PP, HDPE, LLDPE), Polyamides, ABS, styrenic polymers, polyesters, synthetic elastomers, adhesives, and many other organic substrates and in particular for engineering thermoplastic elastomers with a high extraction resistance. In combination with sulphur containing co-stabilizers, such as Hostanox SE 10 and Hostanox SE 4, it leads to a pronounced synergistic effect concerning long term thermal stability respectively oven life.
Hostanox O 3 powder is recommended especially for the applications where polymers and/or binders are cured at elevated temperature and need thermo-stabilization, e.g. powder coatings, coil coatings and specific solventborne coatings.
