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.

Application Field:
Ethanol has many USES.First of all, ethanol is an important organic solvent, widely used
in medicine, paint, sanitary products, cosmetics, oils and other fields.
Secondly, ethanol is an important basic chemical raw material, which is used for manufacturing acetaldehyde, ethylamine, ethyl acetate, acetic acid, etc., and derives many intermediates of medicine, dye, paint, perfume, synthetic rubber, detergent,
pesticide and other products.Thirdly, 75% ethanol aqueous solution has strong bactericidal ability and is a commonly used disinfectant in medical treatment.Finally, similar to methanol, ethanol can be used as an energy source. In 2017, various ministries and commissions in China jointly issued relevant policies to promote the nationwide use of vehicle ethanol-fueled gasoline by the end of 2020.

Dimethylformamide (DMF) is a clear, colorless, hygroscopic liquid with a slight amine odor. The solvent properties of DMF are particularly attractive because of the high dielectric constant, the aprotic nature of the solvent, its wide liquid range and low volatility. It is frequently used for chemical reactions and other applications, which require a high solvency power. The product is known as a universal solvent. The high solubility of polyacrylonitrile in DMF, together with the good miscibility of DMF in water makes DMF the preferred solvent to produce acrylic fibers. Also, the spinning of polyurethane based elastomers is performed from DMF based solutions. Another significant application is the use of DMF as a solvent for polyurethane-based coatings on leather and artificial leather fabrics.
Application: It is used in the chemical industry as a solvent, an intermediate, and an additive; for example, in the production of pharmaceuticals, synthetic fibers, resins, agrochemicals, petrochemical industry etc.
