HPMC (Hydroxypropyl Methyl Cellulose) China Manufacturer
What is HPMC?
InnoNew® Hydroxypropyl Methyl Cellulose (HPMC) is a non-ionic cellulose ether widely used in construction materials to improve water retention and workability. It functions as a water retention agent, thickener, and rheology modifier, significantly improving workability, adhesion, and durability in dry mix mortar systems.
Key Benefits:
Excellent water retention → prevents rapid drying
Improved workability and open time
Enhanced adhesion strength
Anti-sagging performance in vertical applications
Stable viscosity across different formulations

FAQ:
Q1: What is HPMC?
A: HPMC (Hydroxypropyl Methylcellulose) is a non-ionic cellulose ether derived from natural polymer cellulose. It is widely used as a thickener, water retention agent, stabilizer, and film-forming agent in construction, pharmaceuticals, and coatings.
Q2: Is HPMC suitable for tile adhesive?
A: Yes, it enhances bonding and open time. HPMC is often used together with Redispersible Polymer Powder to improve flexibility and adhesion.
Q3: What viscosity grades are available for HPMC?
A: HPMC is available in a wide range of viscosities, typically low viscosity (5,000-15,000 mPa.s), Medium viscosity (40,000-100,000 mPa.s) and high viscosity (150,000-200,000 mPa.s), different applications require different viscosity grades.
Q4: Can HPMC be customized?
A: Yes, InnoNew Material is professional HPMC manufacturer, we can provide customized viscosity, tailored water retention performance, and specific grades to meet your specific project requirements
