9004-36-8 Usage
Description
CELLULOSE ACETATE BUTYRATE is a versatile organic cellulose ester that combines the properties of cellulose acetate and butyrate. It is known for its increased flexibility, moisture resistance, solubility, and compatibility with resins. The material's properties can be tailored by adjusting the butyryl content, which in turn affects its hardness, tensile strength, and heat resistance.
Uses
Used in Plastics Industry:
CELLULOSE ACETATE BUTYRATE is used as an injection moulding material for applications requiring toughness, such as tabulator keys and tool handles. The increased butyryl content enhances flexibility and moisture resistance, making it suitable for these uses.
Used in Packaging Industry:
CELLULOSE ACETATE BUTYRATE is used as a puncture-resistant film for packaging materials, providing protection and durability to the packaged products.
Used in Coating Industry:
CELLULOSE ACETATE BUTYRATE is used in lacquers for various items, including cables, fabrics, and furniture. Its compatibility with resins and solubility make it an ideal choice for coating applications.
Used in Coating Applications:
CELLULOSE ACETATE BUTYRATE is the most commonly used organic cellulose ester for coating applications due to its versatility and ability to be tailored for specific needs.
Used in Contact Lens Industry:
CELLULOSE ACETATE BUTYRATE is used as a contact lens material, specifically for hydrophobic lenses. Its properties provide comfort and durability for wearers.
Preparation
Cellulose acetate-butyrate (CAB) is prepared in a manner similar to that
described previously for cellulose acetate. Esterification is carried out using a
mixture of acetic anhydride and butyric anhydride with sulphuric acid as
catalyst and then the product is slightly hydrolysed. Depending on the
reaction conditions, various products may be obtained; commercial materials
generally have about 1-2 butyryl groups per glucose residue.
Check Digit Verification of cas no
The CAS Registry Mumber 9004-36-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 9004-36:
(6*9)+(5*0)+(4*0)+(3*4)+(2*3)+(1*6)=78
78 % 10 = 8
So 9004-36-8 is a valid CAS Registry Number.
