A: Chemic HPMC (hydroxypropyl methyl cellulose) is a non-ionic cellulose ether derived from natural polymers. It is widely used as a thickener, binder, and water-retention agent in construction materials, pharmaceuticals, and personal care products.
A: Chemic HPMC enhances workability, adhesion, and water retention in cement-based products like tile adhesives and mortars. It reduces cracking and extends open time for easier application.
A: Yes, chemic HPMC undergoes hydroxypropyl and methyl group substitutions, making it more soluble in cold water and thermally reversible compared to untreated cellulose. This modification improves its performance in diverse industrial applications.
A: Yes, pharmaceutical-grade chemic HPMC is safe for use as a coating agent, binder, or controlled-release matrix in tablets. It must meet strict purity standards outlined in pharmacopeias like USP or EP.
A: Store chemic HPMC in a cool, dry place below 30°C (86°F) with moisture-proof packaging. Avoid direct sunlight and mix thoroughly during preparation to prevent clumping in aqueous solutions.
