Hydroxypropyl Methyl Cellulose (HPMC): white or white fibre-like powder or granules belonging to various non-ionic types of cellulose blends. This product is a semi-synthetic, non-reactive viscoelastic polymer.
Hydroxyethyl Cellulose (HEC): white or yellow, odourless, non-toxic fibrous or solid powder. The main raw materials are alkaline cellulose and ethylene oxide etherification, a non-ionic soluble cellulose ether.
Hydroxypropyl methyl cellulose (HPMC): used as a thickener, dispersant and stabiliser in the coatings industry. Good phase solubility in water or organic solvents. It is also used as a paint stripper; as a dispersant in the production of polyvinyl chloride, and is the main auxiliary in the preparation of PVC for suspension polymerisation; it is also widely used in the leather, paper products, fruit and vegetable preservation and textile industries.
Hydroxyethyl cellulose (HEC): used as an adhesive, surfactant, colloidal protectant, dispersant, emulsifier and dispersion stabilizer. It has a wide range of applications in coatings, inks, fibres, dyeing, paper making, cosmetics, pesticides, mineral processing, oil extraction and pharmaceuticals.
Hydroxypropyl methyl cellulose (HPMC): almost insoluble in anhydrous ethanol, ether, acetone; soluble in clear or slightly turbid colloidal solution in cold water.
Hydroxyethyl cellulose (HEC): able to prepare solutions of different viscosity ranges and has good salt solubility for electrolytes.
The production process of hydroxypropyl methylcellulose is mainly a polysaccharide-based ether product produced by alkalinisation and etherification of cotton fibres (domestic). It is not charged itself and does not react with the charged ions in the gelling material, making it stable.The price is a
Hydroxypropyl methyl cellulose is a tasteless, odorless and non-toxic white powder that dissolves in water to form a transparent, viscous liquid. Hydroxypropyl methyl cellulose with adhesion, thickening, emulsification, dispersion, film forming, adsorption, gelling, surface moisture and protective c
