Introduction
|
UV-531 is a
benzophenone type UV absorber for plastics and other organic polymers.
Characterized by its strong, broad range UV absorption
property and excellent polymer compatibility, UV-531 exhibits very effective protection of polymers against UV
lights exposure. UV-531 retards yellowing, embrittlement and mechanical degradation of the
polymers when properly used.
UV-531
is particularly recommend for the light stabilization of PP, PE and PVC. It
is also effective in polycarbonate, polyester, acrylics, EVA, and other
polymers.

|
Advantage
|
• Very high photostability for its strong
ability to absorb light especially in UV region(300-400nm)
• No effect on the odor of the resins.
• Very low vapor pressure, prevents product
from loss during processing.
• Very high heat resistance,
without significant degradation or volatility at proper extrusion
temperature.
• High purity, no adverse effects due to
impurities.
|
|
Applications
|
1. Polypropylene : 0.2~0.5% on the polymer weight
2. Polyethylene : 0.2~0.5% on the
polymer weight.
3. Polyvinyl chloride: 0.5~2% for plasticized PVC by
weight basis
about 0.5% for rigid PVC by weight basis.
|
|
Toxicity & Safety
|
UV-531 can be safely handled without
irritation caused to the skin.
|
|
Package
|
In 25 kg carton drum with inner plastic
bag.
|
|
Storage
|
In a closed system and dry, dark place
without any light exposure.
