Melting Range  167-171 °C (333-340 °F)
Solubility Soluble in acetone, ethyl acetate, iso-propanol, methanol
Insoluble in water
Application Plastics
Hostanox O 3 pills 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.

Application Coatings
Hostanox O 3 pills 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.
