Premium HPMC Hydroxypropyl Methylcellulose China Factory and Suppliers
Hydroxypropyl Methylcellulose (HPMC) is a high-performance, non-ionic cellulose ether derived from natural polymer materials. It serves as a versatile additive across multiple industries, acting as a powerful thickener, stabilizer, and water-retention agent. Depending on the specific application needs, our HPMC is engineered into two primary categories: instant dissolving and hot dissolving, ensuring optimal compatibility with your formulation requirements.
From high-end personal care products like shampoos and toothpastes to industrial-grade construction materials like tile adhesives and wall putties, our HPMC provides exceptional rheological properties. By improving workability and preventing cracking or drooping, it ensures a professional finish and long-term durability in every application, making it an indispensable component for specialty chemical manufacturing.

Frequently Asked Questions
Instant dissolving HPMC can be dissolved in room temperature water and is ideal for detergents and pharmaceuticals. Hot dissolving HPMC requires temperatures above 60°C and is primarily used in construction and ceramics for better water retention.
Purity can be checked in three ways: by burning (lower ash ratio means higher purity), by weighing (higher density indicates higher purity), and by checking fluidity (smoother flow suggests better quality).
For tile adhesives, EIFS mortar, and wall putties, hot dissolving HPMC is recommended as it provides critical water retention and prevents the mortar from drooping or cracking.
Yes, the instant dissolving type of HPMC is widely used in shampoos, liquid soaps, and toothpastes as a thickener and emulsifier due to its high permeability and stability.
Yes, we provide free samples to ensure our quality meets your standards. We can provide samples from different batches to demonstrate our quality stability; the buyer only covers the air shipping cost.
HPMC acts as a water retention agent that prolongs open time and ensures the putty is anti-drooping and anti-cracking, significantly improving the overall workability and final finish.
