Two common plastics based on the cellulose molecule are cellulose acetate (CA) and cellulose acetate-butyrate (CAB). Cellulose acetate is not used for construction purposes, but CAB can be made resistant to weathering and is used in piping for gas and chemicals. Cellulosics are also used in coating compounds and adhesives.
