Cellulose diacetate rod is a rod-like material made from cellulose diacetate, the following is its detailed introduction:
Chemical composition: Cellulose diacetate is cellulose derivatives obtained by the acetylation reaction of cellulose, it is generated by the reaction of natural cellulose and acetic anhydride under the action of catalyst, about 2/3 of the hydroxyl group in the molecule is acetylated, with good chemical stability and physical properties.
Physical property
Appearance: Usually white or transparent rod, smooth surface, uniform texture.
Density: The density is generally between 1.28-1.33 g/cm³, which is relatively light.
Hardness: has a certain hardness and mechanical strength, is not easy to break, can maintain a better shape.
Thermal properties: The glass transition temperature of cellulose diacetate is about 180-200 ℃, and it will soften and deform when heated to a certain temperature, and can be hot-processed.
Main feature
Good plasticity: Products of various shapes can be made by injection molding, extrusion and other processing methods, suitable for mass production.
Low hygroscopicity: under general environmental conditions, the hygroscopicity is low, can maintain dimensional stability, and is not easy to affect the performance due to moisture.
Biocompatibility: It has good biocompatibility, no obvious stimulation to human tissues, and has certain applications in the medical field.Optical performance: With good optical transparency, it can be used to manufacture products with optical performance requirements.
Application field
Tobacco filter: It is one of the main application areas of cellulose diacetate bar, which can effectively filter tar and other harmful substances in cigarettes and improve the taste of smoking.
Medical supplies: can be used to manufacture syringe push rod, dental base and other medical products, its biocompatibility and mechanical properties to meet the requirements of medical use.
Glasses frame: Using its good plasticity, aesthetics and comfort, it can be made into various styles of glasses frame, which is loved by consumers.
Electronic and electrical: It can be used as an insulating material in electronic and electrical components, and its good thermal stability and mechanical properties can ensure the safety and reliability of the components during use.
