- Advantages
- In the production of rosin esters, BNX 1425P enables shorter reaction times and gives products characterized by reduced discoloration, a low acid number, and improved heat stability
- In PET, BNX 1425P provides faster solid-state polymerization, improved color, and reduced generation of acetaldehyde
- Non-discoloring
- Excellent resistance to migration and extraction
- Low-volatility during polycondensation and high temperature processing
- Extensive FDA clearances

- Applications
BNX 1425P is particularly useful as a stabilizer and esterification catalyst in rosin esters and in PET and other thermoplastic polyesters. It is also effective for the stabilization of polyolefins (particularly polypropylene fibers), cross-linked elastomers, and specialty adhesives.
- Guidelines for Use
In rosin esters, recommended use levels generally range from 0.05 to 1% by weight. BNX 1425P can be used in combination with other additives in rosin esters, including antioxidants, disproportionation agents, and light stabilizers. In PET, recommended use levels range from 0.01 to 0.2% by weight. The product may be added at different stages in PET production, for example in slurry preparation (as a solution in ethylene glycol), during the esterification step, or after finishing (by extrusion compounding). In processes utilizing phosphoric acid, sequential addition is necessary to avoid undesired interactions. BNX 1425P can be used in combination with other additives in polyesters, including antioxidants, UV absorbers, and benzoate light stabilizers. In all applications, the exact formulation to be used is dependent on the substrate, performance requirements, and other factors, and should be determined by the user based on testing to simulate actual conditions of use.
