  Applications
  1.Polypropylene : 0.2-0.5wt% based on polymer weight
  2.PVC:
    Rigid PVC : 0.5wt% based on polymer weight
    Plasticized PVC : 0.5-2 wt% based on polymer weight
  3.Polyethylene : 0.2-0.5wt% based on polymer weight
  
  This product is a light stabilizer with good performance, capable of absorbing the UV radiation 
  of 240-340 nm wavelength with the characteristics of light color, 
  nontoxic , good compatibility, 
  small mobility, easy processing etc. It can protect the polymer to its maximum extent, helps to 
  reduce the color. It can also delay the yellowing and obstacle the loss of its physical function. 
  It is widely applied to PE,PVC,PP,PS,PC organic glass, polypropylene fiber, ethylene-vinyl 
  acetate etc. Moreover, it has very good light-stability effect on drying phenol aldehyde,
   varnish of alcohol and acname, polyurethane, acrylate, expoxnamee etc.
  Storage
  The product may be stored up to two years in a sealed container. Containers should be stored in a cool, dry area. Extended storage at elevated temperatures or exposure to direct heat or sunlight could reduce product life. Keep containers sealed when no in use.
  Packaging and storage
  Inner drum lined with plastic bag, 25KG / barrel (NW)
  Sealed and stored in a dark, dry place
