summarize

Antioxidant 245 is a highly efficient asymmetric hindered phenol antioxidant, which is characterized by high antioxidant efficiency, low volatility, good oxidation resistance and coloration, and significant synergistic effect with auxiliary antioxidants (such as thioester or phosphite ester), and can be used with light stabilizer to give products excellent weather resistance.

use

The antioxidant has good compatibility with polymers, high thermal oxygen resistance, and is suitable for high impact polystyrene, ABS resin, AS resin, MBS resin, polyvinyl chloride, polyformaldehyde, polyamide, polyurethane, hydroxylated styrene butadiene rubber and styrene butadiene latex. In PVC polymerization, it is also a chain terminator (0.02% ~ 0.05%). In the field of polyurethane materials, it can be used in RIM, TPU, spandex, polyurethane adhesive, sealant and other products. It can be combined with auxiliary stabilizers (such as thioesters, phosphite esters, phosphite esters, lactone), light stabilizers and its functional stabilizers.
