HPMC is widely used in building materials, coatings, synthetic materials, ceramics, medicine, food, textile, agriculture, cosmetics, tobacco and other industries. Domestic HPMC is practically building grade. In building grade, putty powder is used In a large amount, about 90% of which is used for putty powder, and the rest is used for cement mortar and glue.
The content and viscosity of hydroxypropyl group are two indicators that most users are concerned about. High hydroxypropyl content, water retention is generally better. Viscosity, water retention, relative (rather than absolute) is better, and viscous, better in cement mortar.
Soak the pure cellulose (purified cotton / wood pulp) in an aqueous caustic soda and organic solvent mix.
React the resultant alkaline cellulose with etherifying agents, such as alkyl halides or alkylene oxides,
Recover the solvents and wash the product,
Dry and mill the ethereified product.
applications are primarily focused on building materials and paints,although it has a wide range of industrial applications including, not limited to:
Oil field operations
