Celix Cellulose Co., Ltd, is an integrated chemical cellulose manufacturer with in-house R&D, factories, and global sales sites.
Our products include HPMC, HEC, MHEC, VAE RDP, PCE, PVA, Defoamers, PP fibers, HPS, SHP and Gypsum Retarder.
In the technical parameters of cellulose ether (HPMC, HEC, MHEC, etc.), viscosity is one of the most concerned indicators for customers. Commonly used detection methods mainly include NDJ rotational viscometer (common standard in China) and Brookfield viscometer (international common standard).
Key Differences
Standardization: NDJ is more localized (China GB standard), Brookfield is globally standardized (ASTM/ISO).
Viscosity Range: Brookfield covers a much wider range and high viscosities. Celix uses the Brookfield standard to stats the viscosity grade of HPMC.
Precision: Brookfield is generally considered more accurate and repeatable.
Market Recognition: Overseas customers usually expect Brookfield values; domestic construction users often reference NDJ values.
