Hydroxypropyl methylcellulose Product Description:
Hydroxypropyl methylcellulose (INN name: Hypromellose), also simplified as hydroxypropyl methylcellulose (HPMC), is a variety of nonionic cellulose mixed ethers. It is a semi-synthetic, inactive, viscoelastic polymer .This product is industrial grade HPMC, mainly used as the dispersing agent for PVC production and as the main assistant used in producing PVC suspension polymerization.
It is also used as thickener, stabilizer, emulsifier, excipient, water retention agent, and film-forming agent etc.in producing petrochemicals, building materials, paint removers, agricultural chemicals, inks, textiles, ceramics, paper. cosmetics and other products.
Hydroxypropyl Methyl Cellulose is a non-ionic cellulose ether made through a series of chemical processes, with the natural polymer cellulose as the raw material. HPMC can be used in building materials, coating industry, synthetic resin, ceramic industry, medicine, food, textile, agriculture, daily chemicals and other industries.
Industrial-grade hydroxypropyl methyl cellulose used in mortar is distinguished by viscosity. Generally, the following types are commonly used Low viscosity: 400 is mainly used for self-leveling mortar. Reason: low viscosity, good leveling, high mortar density. Medium and low viscosity: 20000-400000
Hydroxypropyl methyl cellulose ether-HPMC, as an auxiliary additive widely used in the field of building materials, is mainly used for water retention, thickening and improving the workability of the finish product. Water retention rate is often one of the core indicators for selecting high-quality
