Cellulose Acetate Butyrate (CAB), commonly known as butyrate, is resistant to ultraviolet rays, has a lower moisture absorption than acetate and has an extremely high impact strength.

Cellulosics, as a group, are characterized by good strength, toughness, and high surface gloss. In addition, they have good chemical resistance, good clarity, sparkle, and will take decoration readily. Cellulose acetate butyrate is tougher than acetate and has lower moisture absorption. It resists weathering and has excellent transparency. Although it is adversely affected by alcohol, alkalis, paint removers, and acetones, it is resistant to most household chemicals. Additionally, CAB is resistant to the harmful effects of ultra-violet radiation.
