Hydroxyethyl cellulose (HEC) is a non-ionic soluble cellulose ether derivatives that can coexist with many other water-soluble polymers, surfactants, and salts. HEC has the properties of thickening, suspension, adhesion, emulsification, stable film formation, dispersion, water retention, anti-microbial protection and colloidal protection. It can be widely used in coatings, cosmetics, oil drilling and other industries.
The main properties of Hydroxyethyl cellulose(HEC) are that it can be dissolved in cold water and hot water, and has no gel characteristics. It has a wide range of substitution, solubility and viscosity. It has good thermal stability (below 140C) and does not produce under acidic conditions. precipitation. The hydroxyethyl cellulose solution can form a transparent film, which has non-ionic features that do not interact with ions and have good compatibility.
Sodium carboxymethyl cellulose(CMC), also known as: Sodium CMC, cellulose gum, CMC-Na,is cellulose derivatives,which is the most widely used and the largest amount in the world. it is a cellulosics with a glucose polymerization degree of 100 to 2000 and a relative molecular mass of 242.16. White fibrous or granular powder. Odorless, tasteless, tasteless, hygroscopic, insoluble in organic solvents.
CMC is an anionic cellulose ether, white or milky white fibrous powder or granule, density 0.5-0.7 g/cm3, almost odorless, tasteless, and hygroscopic. Easily disperse in water into a transparent gel solution, insoluble in organic solvents such as ethanol. The pH of 1% aqueous solution is 6.5 8.5. When pH 10 or
Hydroxypropyl Methylcellulose (HPMC) or hypromellose is a derivatives of Methyl cellulose . It is a white or off-white fibrous or granular cellulose ether powder. It is currently the cellulose with the best performance in the world, integrating thickening, suspending, dispersing, emulsifying and stabilizing. Hydroxypropyl methyl cellulose (HPMC) is non-toxic, easy to use, and easily soluble in water. It is a polyanion in aqueous solution and has unique physical properties.
Redispersible Polymer Powder (RDP) is redispersible latex powders, based on vinyl ethylene acetate emulsion,which are divided into ethylene/vinyl acetate copolymer, vinyl acetate/vinyl tertiary carbonate copolymer, acrylic acid copolymer, etc., powder bonded after spray drying It uses polyvinyl alcohol as a protective colloid. This kind of powder can be quickly redispersed into emulsion after contact with water, because the redispersible latex powder has high bonding ability and unique properties, such as: water resistance, construction and heat insulation, etc.
Hydroxypropyl Methyl Celluloseare types of non-ionic cellulose ether, which are a powder of white to off white color, thatfunction as a thickener, binder, film-former, surfactant, protective colloid, lubricant, emulsifier and suspension and waterretention aid. In addition, there types of cellulose ethers exhibit properties of thermal gelation, metabolic inertness, enzy meresistance, low odor and taste, and PH stability.
Due to the myriad of properties, HPMC is often used to substitute many other additives with lower concentration, making HPMC anincredibly efficient and effective additive in area of adhesives, construction, foods, household products, pharmaceuticals and etc.
Carboxymethyl Cellulose (CMC) is a high-quality, water-soluble polymer used as a thickener, binder, and stabilizer in food, pharma, textiles, paper, and personal care industries. It enhances texture, improves shelf life, and offers excellent viscosity control. Available in powder form and various grades for both food and industrial use.
Hydroxypropyl Methylcellulose (HPMC) is a versatile, non-ionic cellulose ether derived from natural sources, widely used as a thickener, binder, film-former, and stabilizer in pharmaceuticals, construction, food, cosmetics, and industrial applications. It offers excellent water retention, high viscosity, and improved texture in end products. HPMC is odorless, tasteless, non-toxic, and available in various viscosity grades in free-flowing powder form.
