Applications
  • RIANOX® 1135R offers excellent antioxidant performance with the convenience of a pumpable liquid. Because of its low volatility and excellent compatibility, RIANOX® 1135R is particularly well suited to use in forced air cooling processes for polyurethane.
  • The low volatility and excellent compatibilty also helps to prevent fogging in automotive applications and to prevent staining of textiles (e.g. furniture, carpeting, head rests, etc.). The liquid nature and low volatility of RIANOX® 1135R make it a perfect fit where neat liquids, emulsions, suspensions, solutions or melts are an integral part of polymer manufacturing and processing.
