What is Cellulose Acetate Butyrate?
Cellulose acetate butyrate (CAB) is a combined ester polycarbonate derivative of cellulose acetate, which consists of both acetic acid as well as butyric acid functional teams. Compared to cellulose acetate, it has higher weather resistance and lower moisture absorption.The exact properties of CAB compounds depend on the composition of butyric acid and acetic acid functional groups.
CAB is usually used as adhesive or additive in coatings.
The preparation method of cellulose acetate butyrate (CAB) is similar to that of cellulose acetate described previously. The mixture of acetic acid and butyric anhydride is used as catalyst, and sulfuric acid is used as catalyst for esterification, and then the product is slightly hydrolyzed. Different products can be obtained according to different reaction conditions; Commercial materials typically have about 1-2 butyryl groups per glucose residue.
Cellulose Acetate Butyrate Uses
- Call lens product (hydrophobic).
- CAB is one of the most generally made use of organic cellulose ester in paint application.
- Typically, the increase of butyryl web content will certainly boost adaptability, dampness resistance, solubility and compatibility with material; The firmness, tensile stamina and warmth resistance decreased with the boost of butyryl material.
- Cellulose acetate butyrate shot built components are especially difficult, and are used for inventory tricks, device handles and also various other applications; The film is utilized as a slit immune packaging material.
- Cellulose acetate butyrate is also used for the paint, melt and peel coating of cables, fabrics, furniture and other items.

Application of Cellulose Acetate Butyrate
Commonly called butyrate or CAB, it is harder than acetate, with reduced moisture absorption as well as higher softening factor. CAB is made by esterification of cellulose with acetic acid and also butyric acid in the presence of driver. It is specifically suitable for paints, protecting materials, varnishes as well as paints.
Special formulations with good weather resistance and openness are made use of for exterior applications, such as indications, lampshades, and sprinkler system. Butyrate clear tablets can be used for vacuum molding applications. Various other common usages consist of transparent dial covers, TV display covers, device takes care of, and typewriter secrets. Extruded pipelines are utilized for electric channels, pneumatic pipes as well as low-pressure wastewater pipelines. Cellulose acetate butyrate is additionally utilized for cord cladding as well as layer. It is a lot more soluble than cellulose acetate as well as even more miscible with gum tissue. It forms a durable and also adaptable movie. Liquid cellulose acetate butyrate is utilized for varnishes, chemical resistant material coatings and also wire home windows. It can penetrate ultraviolet rays without yellowing or fogging, and is weather resistant.
