Application:
Antioxidant 626 is a kind of
high-effective solid phosphite ester antioxidant, which is superior to other
phosphite ester in the effective protection of polymers color. It is often
blended with phenolic principal antioxidant(such as At-10)to prepare composite
antioxidant which improves the thermo-stability of polymer processing, thus
making it widely applied in PE, PP, PS, PA, PC, ABS and many other polymer
materials.
Packaging and storage:
It is packed in a paper-plastic compound bag lined with a plastic bag, each bag has a net weight of 20kg, and can also be designed according to customer requirements. Store in a dry and cool environment according to general chemicals. The recommended storage time is 12 months.
