1. Basic Information and Parameters

Ethyl cellulose with CAS number 9004 - 57 - 3 is a cellulose ether that is widely used in various industries. Our Factory Supply Ethyl cellulose is of high - quality, sourced directly from the factory at the best price.

Chemical Composition: It is an ethyl ether of cellulose. The degree of substitution (DS), which represents the average number of hydroxyl groups on each anhydroglucose unit that have been substituted by ethoxy groups, typically ranges from 2.2 to 2.6.

Physical Properties: It is a white to light yellow, free - flowing powder. It has a density of approximately 1.07 - 1.18 g/cm³. It is insoluble in water but soluble in many organic solvents such as toluene, ethanol, and chloroform.

2. Uses of the Product

Coating Industry: Ethyl cellulose is widely used as a coating material. In the pharmaceutical industry, it can be used as a film - coating agent for tablets. The coating provides a controlled - release mechanism for drugs, which helps to maintain a stable drug concentration in the body and reduces side effects. In the food industry, it can be used as a coating for nuts and candies to improve their appearance and shelf - life.

Adhesive Industry: It can be used as a component in adhesives. Its good adhesion properties and solubility in organic solvents make it suitable for bonding various materials, such as plastics and metals.

Printing Ink Industry: Ethyl cellulose is used in printing inks to improve the fluidity, adhesion, and drying properties of the ink. It can also enhance the gloss and abrasion resistance of the printed surface.

3. How to Use the Product

Preparation: First, select an appropriate organic solvent according to the application requirements. For example, if it is used in a coating, ethanol or toluene can be used. Then, slowly add the ethyl cellulose powder to the solvent while stirring continuously. The stirring speed should be moderate to ensure uniform dispersion.

Coating Application: For tablet coating, use a tablet coater. Adjust the spraying parameters such as spray rate, atomization pressure, and inlet air temperature to ensure a uniform coating thickness. For food and industrial coatings, spraying or dipping methods can be used.

Adhesive Preparation: Mix the ethyl cellulose with other adhesive components in the appropriate ratio. Heat the mixture if necessary to improve the solubility and bonding performance. Apply the adhesive to the surfaces to be bonded and press them together firmly until the adhesive cures.

4. Detailed Usage Case Studies

Pharmaceutical Tablet Coating: A pharmaceutical company used our ethyl cellulose for tablet coating. They had a new drug that needed a controlled - release mechanism. By using ethyl cellulose as the coating material, they were able to achieve a steady release of the drug over a period of 12 hours. The coating process was optimized by adjusting the spraying parameters. After several tests, they found that a spray rate of 5 ml/min, an atomization pressure of 2 bar, and an inlet air temperature of 60°C gave the best coating quality. The tablets had a smooth and uniform surface, and the drug release profile met the requirements of the clinical trials.

Food Candy Coating: A confectionery manufacturer used ethyl cellulose to coat their candies. They wanted to improve the appearance and shelf - life of the candies. By dipping the candies in an ethyl cellulose solution, they created a thin, transparent coating. The coating not only made the candies more attractive but also protected them from moisture and oxidation. As a result, the shelf - life of the candies was extended from 3 months to 6 months.

User’evaluation of us

"vivalr is my partner for years. Met at 2014 Shanghai CPHI Expo. Not interested then as had stable supplier. In Sep 2016, original supplier couldn't guarantee quality and delivery. Thought of Zhai and his company first. So far, have stable business relationship and good personal friendship."

Marcus Long

" In years of sourcing from China, first found working with Sincere Chemical great. They help in production, delivery and tech, saving time. When first asking Zhai for optical brightener quote, got detailed one with prices, trade details, company info, R&D and production capacity, packaging and raw material control."

Emma Kung

" Hi, I'm Kim, Zhai's partner. Don't like him much (as he never gives more for my prices, haha), but still write customer feedback. Zhai's emails help me understand product and industry. Satisfied with his work ethic. He provides quotes and helps with work details, so I can focus on other things. He's the best supplier for me."
