BNX® 1425P

Technical DataSheet | Supplied by Mayzo

BNX®1425P by Mayzo is phosphonic acid, P−[[3,5−bis(1,1−dimethylethyl)−4−hydroxyphenyl] methyl]−, monoethyl ester, calcium salt (2:1). Acts as an antioxidant and esterification catalyst. In the production of rosin esters, it enables shorter reaction times and gives products characterized by reduced discoloration, a low acid number, and improved heat stability. In PET, it provides faster solid-state polymerization, improved color, and reduced generation of acetaldehyde. It is non-discoloring, exhibits excellent resistance to migration and extraction, low-volatility during polycondensation and high temperature processing and extensive FDA clearances. BNX®1425P by Mayzo is compatible with PET, other thermoplastic polyesters. In PET, recommended dosage is 0.01-0.2% by weight. It has a shelf life of two years.
