FAQ: Professional Technical FAQ for Hydroxypropyl Methyl Cellulose HPMC Q1: What is the main material origin and structure of Hydroxypropyl Methyl Cellulose HPMC ? A: It is synthesized by the etherification of pure, natural cellulose (commonly from wood pulp or cotton linters) to introduce hydrophilic hydroxypropyl and methyl groups. This changes the solubility, thermal gelation, and viscosity properties, forming a linear, high molecular weight polymer with adjusted functional groups ( ACS Publication ). Q2: What viscosity grades can be supplied, and how are they selected for end-use? A: We offer Hydroxypropyl Methyl Cellulose HPMC in viscosity grades ranging from 3,000 to 100,000 mPa·s or more (at 2% aqueous, 20°C). Construction mortars typically use 20,000–40,000 mPa·s, while pharmaceuticals prefer low-medium viscosity. Grade selection is based on required water retention, film thickness, or binding power in formulation. Q3: What are the typical particle sizes and bulk densities of HPMC powders? A: Standard mesh size ranges from 80 to 100 mesh, with bulk density of 0.30-0.55 g/cm³. Customization is available for specialized dispersibility or mixing requirements ( Cellulose Ether Forum ). Q4: Is Hydroxypropyl Methyl Cellulose HPMC compliant with international regulatory and safety standards? A: Yes, HPMC meets GB, ASTM, USP/NF, BP/EP, E464, and JECFA safety criteria for use in foods, pharmaceuticals, and industrial applications. It is non-ionic, non-toxic, and hypoallergenic ( FAO JECFA ). Q5: What is the recommended installation and mixing standard for construction use? A: For dry-mix mortar, use 0.2-0.5% by weight, ensuring even dispersion prior to water addition. Follow EN 998-1 or ASTM C270 for mortar mixing; always pre-wet mixing equipment and blend gradually into dry components to avoid lump formation. Q6: How does film formation and thermal gelation enhance material performance? A: Thermal gelation between 58–90°C imparts superior sag resistance and stability to cementitious layers. Film-forming properties ensure encapsulation of aggregates, improved finish, and dust control for food/pharma-grade applications ( PubMed ). Q7: Are there options for “rapid-dissolving” or “surface-modified” Hydroxypropyl Methyl Cellulose HPMC ? A: Yes, we offer fast-dispersing, self-wetting, and surface-treated HPMC grades to optimize mixing efficiency, especially for industrial-scale mortar, detergent, or pharmaceutical production. These grades exhibit quick hydration and low lumping ( Cellulose Ether Forum ). Why Choose HeBei ShengShi HongBang Cellulose Technology CO.,LTD. as Your Hydroxypropyl Methyl Cellulose HPMC Supplier?
