Various grades of Eastman cellulose acetate butyrate, especially CAB 381-20, have demonstrated a wide range of benefits for cast acrylic sheet, which can be used in lightweight curved glazing, display shelves, outdoor signs, and display boards. Benefits to producers include:

  • Elimination of flooding and floating of colored pigments in polymerized acrylic sheets
  • Reduction of titanium dioxide sedimentation during polymerization, providing uniform distribution throughout the cast sheet
  • Improvement of metallic flake and pearlescent flake alignment
  • Reduction of extender haziness or clouding, particularly for acrylic sheets containing barium sulfate
