Characteristics and uses :
UV absorbers UV-531 is a high
performance and efficient Anti-
aging agents, can absorb UV 240-
340 nanometers, with light color,
nontoxic, good compatibility,
small relocation and easy to
process characteristics. It is
the largest polymer protective
effect, and help to reduce the
color, while delaying and
obstructing the yellowed loss of
physical properties. It is widely
used to PE, PVC, PP, PS, PC,
PMMA, PP fibers and ethylene
Storage and packaging :
UV absorbers UV-531 non-toxic,
non-flammable and difficult to
burglary, corrosion, good storage
stability.
