Products Description
(Hydroxypropyl methylcellulose, abbreviated as HPMC), is a compound belonging to non-ionic cellulose mixed ethers. It is a semi-synthetic, inactive, and viscoelastic polymer. It is often used as a lubricant in ophthalmology and serves as an excipient or a matrix material in oral medications. It is commonly found in various types of commercial products.
As a food additive, hydroxypropyl methylcellulose can play the following roles: emulsifier, thickener, suspending agent and an alternative to animal gelatin.
Uses
HPMC is widely used in various industries such as construction materials, coatings, synthetic resins, ceramics, medicine, food, textiles, agriculture, cosmetics, and tobacco. According to its application, HPMC can be classified into: construction grade, food grade and medicine grade. Currently, most of the domestic products are of construction grade. Among them, putty powder is used in large quantities, accounting for approximately 90% of the total usage, and the rest is used for cement mortar and glue.

Features of HPMC
01.SOLUBILITY
Can be dissolved in water, its highest concentration is only determined by the viscosity, the solubility changes with the viscosity, the lower the viscosity, the greater the solubility.
02.NON-IONIC
The product is a non-ionic cellulose ether, and it is not a polyelectrolyte, so it is relatively stable in aqueous solution in the presence of metal salts or organic electrolytes, but excessive addition of electrolytes can cause gelation and precipitation
03.SURFACE ACTIVITY
Due to the active function of the aqueous solution, it can be used as a colloidal protective agent, emulsifier and dispersant
04.THERMAL GELS
When the product aqueous solution is heated to a certain temperature, it becomes opaque and the gel forms a precipitate. However, when it is continuously cooled, it returns to the original solution state. The temperature at which this gelation and precipitation occurs mainly depends on their lubricants and suspending agents. Protective colloid. Emulsifier, etc.
05.FILM FORMATION
Can form a transparent, tough and flexible film with good oil resistance and water resistance
06.MILDEW RESISTANCE
Has relatively good anti-fungal ability. Good viscosity stability during long-term storage.
