It is also effective for the stabilization of polyolefins particularly polypropylene fibers , cross-linked elastomers, and specialty adhesives.
Advantages In the production of rosin esters, BNX P enables shorter reaction times and gives products characterized by reduced discoloration, a low acid number, and improved heat stability In PET, BNX P 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 Guidelines for Use In rosin esters, recommended use levels generally range from 0.
BNX P 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. 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 P 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.

ANTIOXIDANT 1425 (IRGANOX 1425)
Versatile Application Range The applications are as manifold as the properties of our products: Explore the various application possibilities! Traditionally, aliphatic polyamides are stabilized with small amounts of copper salts. Read more Additives for Polycarbonate Polycarbonate discolors as a manifestation of autoxidation. This is of major concern, because, besides its high impact strength, the primary commercial properties of PC are its optical properties such as transparency. Read more Additives for Polyethylene Sterically hindered phenols are powerful stabilizers for the melt processing of polyolefins.
