Description

Cyanoethyl Cellulose CAS NO 9004-41-5 is a chemically modified cellulose ether where hydroxyl groups are substituted with cyanoethyl groups, imparting unique dielectric and thermoplastic properties. This modification is critical for applications requiring materials with specific electrical characteristics and enhanced solubility in organic solvents. It is an essential polymer for manufacturers in the electronics, specialty coatings, and advanced material synthesis sectors seeking to improve product performance.

Application

• Dielectric Films and Capacitors: Used as a key component in the formulation of high-performance dielectric layers and insulating films for electronic components.
• Specialty Adhesives and Sealants: Serves as a rheology modifier and binder in adhesives requiring specific solubility in organic systems.
• Advanced Composite Materials: Employed as a matrix or additive in composites to enhance electrical properties and processing characteristics.
• Controlled-Release Pharmaceutical Coatings: Utilized in specialty coating formulations for drug delivery systems due to its film-forming ability.
• Lithographic and Photoresist Materials: Acts as a polymer resin in photosensitive compositions for printed circuit boards and microelectronics.
• Gas Separation Membranes: Investigated for use in polymer membranes due to its tailored permeability and chemical resistance.

Quality Control

Our Cyanoethyl Cellulose is produced under a stringent quality management system. Each batch is tested to ensure consistent degree of substitution, viscosity, purity, and moisture content. Certificates of Analysis (COA) detailing all relevant specifications are provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect material properties.
