Hydroxypropyl Methyl Cellulose(HPMC) problems
Hydroxypropyl Methyl Cellulose(HPMC) problems 1. What are the main technical indicators of HPMC? The hydroxypropyl content and viscosity, which most users care about are these two indicators. If the hydroxypropyl content is high, the water retention is generally better. 2. What is the viscosity of HPMC? Putty powder is generally 100,000, the mortar is required […]
