HPMC HP — Professional Hydroxypropyl Methylcellulose HP Grade for Demanding Formulations

As a professional HPMC HP manufacturer, we supply hydroxypropyl methylcellulose HP grade with a full viscosity range from 300 to 200,000 mPa·s, water retention of 90% or higher and stable gelation behavior — the performance backbone for construction mortars, pharmaceutical formulations and industrial applications worldwide.

What Is HPMC HP?

HPMC HP is a non-ionic cellulose ether produced from refined natural cellulose through precisely controlled etherification. The HP grade is defined by a methoxyl content of 19–30% and a hydroxypropyl content of 4–12%, a substitution balance that gives the polymer its signature combination of cold-water solubility, thermal gelation and thickening power.

In practical terms, this means HPMC HP dissolves rapidly without lumping, thickens predictably across the entire 300–200,000 mPa·s viscosity spectrum, and holds water where your formulation needs it. Its water retention rate of at least 90% keeps cement-based systems workable long after mixing, while its neutral pH of 6.0–7.0 makes it compatible with sensitive binders and additives.

Whether you are engineering a self-leveling floor compound or refining a specialty coating, HPMC HP delivers repeatable rheology from batch to batch, backed by a full certificate of analysis for every shipment.

Why Source HPMC HP From Us

HPMC HP Frequently Asked Questions

What does HP mean in HPMC HP?

HP identifies a refined grade with a methoxyl content of 19–30% and a hydroxypropyl content of 4–12%, engineered for applications where stable viscosity, high water retention and consistent gelation behavior at 65–75°C are required.

Which HPMC HP viscosity grade do I need?

Our HPMC HP spans 300–200,000 mPa·s. Lower viscosities suit self-leveling systems and spray applications, mid-range grades serve tile adhesives and renders, and high-viscosity grades maximize water retention where mortar workability is critical.

Why is water retention so important in HPMC HP?

With a water retention rate of at least 90%, HPMC HP prevents premature moisture loss from cement and gypsum systems, ensuring complete hydration, stronger binders and longer open time before initial set.

What is your minimum order quantity?

MOQ is 500 kg for standard HPMC HP grades. Trial quantities of 25 kg can be arranged for qualification testing, and free samples are available before any commitment.

How should HPMC HP be stored?

Store in the original sealed bag in a dry, ventilated area. Properly stored HPMC HP has a shelf life of 24 months without measurable viscosity loss.

Can you match competitor specifications?

Send us the competitor product data sheet and we will match or improve the substitution profile and viscosity within our HPMC HP specification range.
