Overview

Description

Ethyl cellulose is the ethyl ether of cellulose, a long-chain polymer with β-anhydroglucose as a unit linked by acetal, and is one of the most widely used water-insoluble cellulose derivatives. Ethyl cellulose has the functions of bonding, filling, film-forming, etc. It is used for resin synthesis of plastics, coatings, rubber substitutes, inks, insulating materials, as well as adhesives, textile finishing agents, etc., and can also be used in agriculture and animal husbandry. Used as animal feed additives, used as adhesives in electronic products and military propellants.

Features

·Good thermal stability and excellent thermoplasticity
·Good flexibility
·Good dielectric
·Excellent alkali resistance, weak acid resistance
·Good anti-aging performance
·Good salt resistance, cold resistance and moisture absorption resistance

Application

·Used as tablet binder and film coating material
·Used as a matrix material blocker to prepare various types of matrix sustained-release tablets
·Used as mixed material to prepare coated sustained-release preparations and sustained-release pellets
·Used as an encapsulation excipient to prepare sustained-release microcapsules, so that the drug effect can be released continuously
·Used as dispersant, stabilizer and water-retaining agent in various pharmaceutical dosage forms
