HPMC
HPMC is derived from cellulose etherized by Methyl Chloride and propylene oxide. These kinds of cellulose could come from wood or cotton. So HPMC may be referred to partially natural polymers.
HPMC has many prominent properties, such as cold-water-solubility, water retention, lubrication, thickening, binding, Surface activity etc. Therefore HPMC can be used as thickeners, binders, water retention agents, suspending polymerization agents, emulsion polymerization agents and so on.
HPMC is widely applied to various dry-mix mortar products, EIFS, plaster, cement-based tile adhesives, tile grouts, self-leveling mortar, gypsum-based mortar, skim coat included. You can obtain easy workability, consistency, pseudoplastic rheological performance, high water retention, improved wetting ability, excellent open time and high adhesion strength via one or a combination of so many useful properties of HPMC.
Our HPMC products are available in various viscosity grades, ranging from 300 to 200000 cP (2% solution at 20℃). Because the viscosity of a solution depends on the concentration of HPMC, so you can obtain the suitable viscosity you want in your formulation by choosing a specific product and a concentration.
We have food grades for food and drug applications that are recognized as additives by related stangdard or legislation.
Our HPMC products are available in two different forms, i.e. general powder and surface-treated powder. The two forms have different dissolving method. The surface-treated powder can be added directly to aqueous system because this product can be immediately dispersed in water rather than agglomerate. The powder is cross-linked by multiple aldehyde in the process of production, resulting in the delayed dissolution of HPMC. On the contrary, the general powder, i.e. untreated product, could agglomerate unless it is thoroughly dispersed.
