Hydroxypropyl methylcellulose (Hypromellose), also known as hydroxypropyl methylcellulose, is a type of nonionic cellulose mixed ether. It is a semi-synthetic, inactive, viscoelastic polymer that is often used as a lubricant in ophthalmology or as an excipient or excipient in oral medications.
HPMC (hydroxypropyl methylcellulose) is a multifunctional additive that is widely used in many industries.
Construction industry: HPMC is widely used in the construction industry, including but not limited to improving the water retention and construction performance of mortar, improving the adhesion and flexibility of tile adhesives, enhancing the waterproof performance of cement-based waterproof mortar, improving the crack resistance of self-leveling floor mortar, and ensuring sufficient hydrophobicity and adhesion in repair mortar. In addition, it is also used to improve the bonding strength, flexibility, aging resistance, impermeability and moisture resistance of interior and exterior wall putties, as well as to improve water retention in masonry plaster mortar and improve the ease of construction operation.
Pharmaceutical industry: HPMC plays an important role in the pharmaceutical industry as a thickener, solvent and sustained-release agent for tablets, as well as a coating material, film material, and rate-controlling polymer material for sustained-release preparations.
Food industry: HPMC is used in plant protein beverages, dairy products, candies, etc. to improve the texture and taste of the products.
Cosmetics industry: HPMC is also widely used in the cosmetics industry as an emulsifier, thickener and moisturizer.
Chemical industry: HPMC is used as a suspending stabilizer and dispersant in the polymerization of vinyl chloride and vinylidene, as well as a thickener and molding adhesive in pesticides and latex.
Other fields: HPMC is also used in fruit and vegetable preservation, textile industry, etc.
In summary, HPMC plays an indispensable role in many industries due to its unique physical and chemical properties. From construction to medicine, food, cosmetics, etc., its application range is wide and important.
