7.It can be used in polyolefine and its polymerized matters.

8.It can be used alone or together with other antioxidants,stabilizers and UV absorbers etc


Guidelines for use:

●In rosin ester: add 0.05%~1% by weight

●In PET: add 0.01~0.2% by weight.it can be added different stages of PET products such as 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. Antioxidant 1425 can be used in combination with other additives in polyesters, including antioxidants, UV absorbers, and benzoate light stabilizers.
