Removing BHT and Nonylphenol from Emulsion SBR Raw Materials for Adhesives and Sealants - (PPT)

摘要

BHT and TNPP have a long history of safe & effective use in SBR. BHT is an economical primary antioxidant for long term stability. BHT functions as H donor to prevent H abstraction from polymer. TNPP is an economical secondary antioxidant for process stability. TNPP is a very effective for decomposition of hydroperoxides. TNPP is also very effective to protect primary AO in process.
