Ethyl cellulose
Product introduction
This product is commonly used as a binder for tablets and granules because of its insolubility in water but its solubility in a variety of organic solvents, etc., can increase tablet hardness and reduce tablet friability, can also be used as a film-forming agent, etc., to improve the appearance, isolate taste, avoid failure with water sensitive drugs, prevent agents from becoming hygromic and metamorphic, and improve the safe storage of tablets, It can also be used as a skeletal material as a skeletal sustained-release tablet.

Ethyl cellulose is abundantly used in coatings. Can also be used as a basic material for solid lubricants for stamping of metal workpieces. In microcircuit printing, ethyl cellulose is used as a color carrier. In the radio industry, it is used as a high-grade insulating material, and in protective coatings as special films such as cladding layers for rocket emitters. They can be used as hot-melt type glue and coatings for cables, paper, textiles, etc., and can also be used as insulation of extrusion wires and as toughness enhancers for plastics. It is also used for pigment grinding bases, for printing inks, for molded plastic powders, for explosive fuse, and in the formulation of vitamins, among others. Used as a removable protective layer for metal parts against corrosion, disfigurement before use, and also as a removable coating to protect friable glassware. There are various uses remaining in adhesives, textile and fibers, medicine and food, and other industries. Industrial grade ethyl cellulose is used in coatings (gel type coatings, hot melt coatings), inks (screen printing inks, photographic concave brushing inks), adhesives, pigment pastes, etc. higher grade products are used in medicine, cosmetics and food, for example, pharmaceutical tablet packaging materials, binders for long-term preparations, etc.
