Frequently Asked Questions About HPMC Grades

What is HPMC and why are there so many numbers like 400, 4000, ma ọ bụ 100000?

HPMC na-anọchi anya hydroxypropyl methyl cellulose. It is a common additive used in construction, nri, and pharmaceuticals. The numbers (400, 4000, 6000, wdg.) show the viscosity of the product in millipascal-seconds (mPa·s). A low number like 400 means thin and fast-dissolving. Ọnụ ọgụgụ dị elu dị ka 200000 pụtara oké na ngwa ngwa mgbe agwakọta na mmiri.
