Anti Reversion Chemicals & Specialties for Rubber Applications
The role of Anti- reversion agents in thermal degradation of sulfur based vulcanizates based on NR, SBR, BR & blends, is of significance to avoid reversion at higher temperatures, or reversion which takes place when vulcanizate are subjected to dynamic stress.
Reduction / Elimination of reversion of vulcanizates, by the incorporation of specific additives or cross linkers is general demand of rubber industry
LANXESS is offering range of Anti- reversion agents like Vuluren, Perkalink 900 as well as Dithiophosphates which when used, avoid reversion.
Vulcuren works during vulcanization providing a less reverting network by introducing crosslinks which are thermally stable, therefore offering higher resistance to reversion.
Perkalink 900 acts by a different mechanism called as repair mechanism .Polysulfide crosslinks, when broken, are repaired by forming new crosslinks which are stable .
Dithiophosphates form well distributed network of monosulfidic or disulfidic crosslinks which are predominantly stable.
By using Anti-reversion agent from LANXESS, we can achieve higher mileage , and longer life..
