Softwood is the dominant raw material used in the production of cellulose plastics. To isolate cellulose fiber from the biomass:

 The wood is cooked or heated in a digester resulting to the production of pulp 
(Pulp chemical composition consists of hemicelluloses and alpha cellulose)

 Residues of resins and lignin are removed by treating the pulp with bleaching agents 
(This bleaching step also contributes to the reduction of hemicelluloses content of the pulp)

 Water is then taken out of the pulp before processing the pulp with high alpha cellulose content 

 The pulp is reacted with certain acids and anhydride to produce cellulose esters used in the production of cellulose plastics 


Cellulose esters are available in various:

  • Types
  • Viscosities
  • Butyryl and acetyl ratios, and
  • Hydroxyl contents

Biopolymers from Wood CelluloseCellulose acetate is one of the most important esters of cellulose. Depending on the way it has been processed, cellulose acetate can be used for great varies of applications such as films, membranes or fibers. Cellulose acetate butyrate can be used as binders and additives in coatings applications for a variety of substrates, including:

  • Plastics
  • Textiles
  • Metal, and
  • Wood

Cellulose acetate propionate is used in various applications such as printing inks, varnishes, nail polish, lacquers, and many more which require:
  • Low odor
  • Clarity
  • Fast solvent release
  • Anti-blocking, and
  • Good adhesion to a variety of substrates
