HPMC ---- Hydroxypropyl Methyl Cellulose
PTMA H SERIES HPMC are types of non-ionic cellulose ether, which are a powder of white to off-white color, that function as a thickener, binder, film-former, surfactant, protective colloid, lubricant, emulsifier, and suspension and water retention aid. In addition, these types of cellulose ethers exhibit properties of thermal gelation, metabolic inertness, enzyme resistance, low odor and taste, and pH stability.
Hydroxypropyl methylcellulose polymers are well-known for their ability to bind, retain water, thicken, form films, and provide many other performance benefits.
Due to the myriad of properties, HPMC is often used to substitute many other additives with lower concentration, making HPMC an incredibly efficient and effective additive in areas of Adhesives, Construction, Foods, Household Products, Pharmaceuticals, and etc.
In cementitous building materials industry, HPMC contributes:
- Improved workability
- Prolonged open time
- Sag and slip resistance
- Better temperature stability
- Increased adhesion strength
