SUNPRAX

Anti-ozonant

Sunprax is used to protect tire against ozone cracks. Ozone reacting with the carbon of a tire causes the polymer chain to break, causing rubber to crack. When Sunprax is blended into a rubber compound, it migrates towards the surface and forms a fine film that provides coating that protects tire against ozone cracks.
