Hydroxypropyl methylcellulose HPMC powder is simply the full chemical name written out beside the abbreviation everyone uses in the trade. Hydroxypropyl methylcellulose is the complete name; HPMC is the shorthand that appears on grade codes, shipping marks and data sheets. When a supplier quotes “HPMC powder,” this is the molecule behind the letters — one nonionic cellulose ether with a specific, verifiable specification.
Because the same abbreviation is used across construction, coatings and many other industries, the name alone never tells a buyer enough. The specification does. A dependable purchase of HPMC powder is confirmed by matching eight values — a white or off-white powder with viscosity of 300–200,000 mPa·s, methoxyl content 19–30%, hydroxypropyl content 4–12%, bulk density 350–450 kg/m³, pH 6.0–7.0, water retention of 90% or more and gelation at 65–75°C — all recorded on a batch certificate of analysis.
Every batch of hydroxypropyl methylcellulose HPMC powder is produced to the same specification and verified in the laboratory before release. A certificate of analysis accompanies each shipment.

| Gelation temperature | 65–75°C |
The difference between a good price and a good purchase is who stands behind the powder. Here is what sourcing directly from the manufacturer delivers at every stage of your supply chain.
When the mill, the grading line and the laboratory belong to one company, the powder you receive next year matches the powder you approved this year. Every batch is checked against the same eight-value specification before release, so your formulation does not have to be re-tuned between shipments.
Your certificate of analysis states appearance, viscosity, methoxyl and hydroxypropyl content, bulk density, pH, water retention and gelation temperature for the exact batch shipped. Customs, quality audits and customer traceability requests are answered by one document, not by email chains.
Tell the factory what your mix needs to do — long open time, high body, fast dissolution — and the right viscosity grade is recommended from a full 300–200,000 mPa·s range. You buy the grade your formula actually needs, not whichever bag a trader happens to stock.
Every grade we supply is shipped in one dependable export format: a standard 25 kg bag with consistent net weight on every unit.
Buying from the people who make the powder means the grade, the COA and the quality standard all come from one place.
Every production batch is tested in our own laboratory before release — viscosity, methoxyl and hydroxypropyl content, pH, water retention rate and gelation temperature are verified against the specification sheet, and a certificate of analysis (COA) is issued for each shipment. Our chemists also help you match the right grade to your formulation and target viscosity.
Beyond the standard 25 kg bag, we offer flexible packaging customization — private-label and OEM bags printed with your brand, custom labelling for local markets, and packing formats arranged to your warehouse or project requirements. Share your specification with the order and we will confirm the details before production.
Yes. Hydroxypropyl methylcellulose is the full chemical name and HPMC is the standard abbreviation; both refer to the same nonionic cellulose ether powder. You can expect the same methoxyl content of 19–30%, hydroxypropyl content of 4–12% and viscosity range of 300–200,000 mPa·s whether the document uses the full name or the initials.
The batch certificate of analysis should state the eight key values: appearance, viscosity, methoxyl content, hydroxypropyl content, bulk density, pH, water retention rate and gelation temperature. Matching these against your required specification is the fastest way to confirm the powder is what you ordered.
Match the grade to the end use: higher viscosity grades give stronger thickening, longer open time and higher water retention for tile adhesives and renders, while lower grades give fluid, fast-dissolving solutions for paints and coatings. Send us your application and target performance and we will recommend the grade from 300–200,000 mPa·s.
A factory-direct purchase means the mill, the grading line and the laboratory belong to one company, so the specification is controlled end to end and every batch ships with its own COA. You also deal directly with the people who can match grades, answer technical questions and keep quality consistent across reorders.
Yes. Free samples with the batch COA ship typically within 24 hours of your inquiry to sales03@eclatmat.com, so you can check dissolution speed, clarity and viscosity in your own lab or plant before committing to a container quantity.
Yes. Our factory exports HPMC powder to more than 40 destinations, with standard export packaging, full shipping documentation and the batch COA included. Tell us the destination port and quantity and we will confirm lead time and incoterms for your order.
Send us your viscosity grade and quantity. We will confirm factory pricing and dispatch a free HPMC powder sample with a COA — typically within 24 hours.
