Cellulose acetate butyrate (CAB) is a thermoplastic material which contains cellulose esters containing acetate and butyrate functional groups.
They are commonly used as binders and additives in coating applications for a variety of substrates, including plastics, textiles, metal, and wood.
Cellulose acetate butyrate (CAB) by Huashihang Chemical is soluble for most solvents, resins and pigments.
Cellulose acetate butyrate Overview
Product name : cellulose acetate butyrate (CAB)
CAS No. : 9004-36-8
EINECS No. : 618-381-2
Formula : C4H8O2XC2H4O2X
Types discription
According to molecular weight, butyryl, acetyl, and hydroxyl content, Huashihang Chemical offers CAB-381-2, CAB-381-20, CAB-381-0.5, CAB-551-0.2.
CAB-381-20 is a high molecular weight cellulose acetate butyrate (CAB) polymer. It is a film former and additive in solvent-based coatings. CAB-381-20 supports a greater degree of film flexibility, wider solubility range, better compatibility with other resins and pigments in formulations. It has better solubility in alcohols, making them useful in curing finishes like baking enamels and acid-catalyzed coatings. CAB-381-20 also facilitate higher crosslinking density in thermoset systems.
CAB-381-2 is a medium molecular weight mixed cellulose ester with moderate butyrate content. It is a film former, resin modifier, and additive in solvent-based inks and coatings.
CAB-381-0.5 is a mixed cellulose ester with low viscosity and medium butyryl content. It is a film forming resin, resin modifier, and additive in solvent-based coatings and inks.
CAB-551-0.2 is a cellulose acetate butyrate (CAB) resin with excellent compatibility. It is primarily a flow and leveling aid in solvent-based and UV-curable coatings and inks.
Cellulose acetate butyrate Use
Coatings and Finishes
Cellulose Acetate Butyrate (CAB) is a important coating material due to its excellent features including adhesion, durability, and resistance to chemicals.
Its main applications are protective coating on metals, plastics, wood, and other materials, which provides a glossy, protective finish.
Films and Sheets
Cellulose Acetate Butyrate can produce transparent and flexible films and sheets. These films have good impact strength, high clarity, and excellent printability,
which makes them suitable for applications such as packaging, laminates, graphics, and overlays.
binding resin in inks
Cellulose Acetate Butyrate (CAB) is as an adhesives and binder including paints, and inks,. It helps improve adhesion, flexibility, and film-forming properties.
This makes it useful in industries such as printing, packaging, and woodworking.
Molding and Extrusion
CAB can be molded or extruded into various shapes and forms, such as rods, tubes, profiles, and injection-molded parts. Its ease of processing, dimensional stability, and impact resistance make it a popular choice in the manufacturing of automotive parts, consumer goods, electrical components, and medical devices.
Eyewear
Cellulose Acetate Butyrate (CAB) is also a material in the production of eyeglass frames and sunglass frames. It offers lightweight, hypoallergenic properties, and can be easily molded into different shapes and designs. CAB frames are also resistant to sweat and cosmetics, making them suitable for prolonged contact with the skin.
3D Printing
Its low melting point, good flow characteristics, and excellent layer adhesion make it suitable for 3D printing.
