Description

Optical Brightener is based on bis-benzoxazole type organic derivative dispersed in the polymer. These Masterbatches are added in polymers to reduce yellowing, improved whiteness, and to enhance the brightness of a product. These Masterbatches function by absorbing the ultraviolet radiation and re-emitting the blue light. These masterbatches are used in order to mask the natural yellowing of plastics

Key Characteristics: –

  • Improves film and fiber brightness
  • Improves product gloss and shine
  • Improves Color of reprocessed material
  • Reduces Yellowness of Reprocessed material/regrinds

Applications:

  • Reprocessed PP resin
  • Reprocessed PE resin
  • Improvement in film brightness and shine
  • Fibers
