Understanding Construction Grade HPMC Hydroxypropyl Methylcellulose (HPMC) is a popular cellulose derivative widely used in the construction industry. It is primarily valued for its binding properties, water retention, and ability to improve the workability of construction materials like cement, mortars, and tile adhesives. Selecting the right construction grade HPMC can significantly impact the quality and […]

Read MoreConstruction grade HPMC ether, also known as hydroxyethyl methyl cellulose (HEMC), is a versatile, white or slightly yellowish, odorless, and tasteless cellulose derivative powder. It’s widely used in the construction industry for its thickening, water retention, adhesion, and film-forming properties. Here’s a closer look at the benefits of using construction grade HPMC ether: Improved workability: HPMC […]
Read MoreConstruction grade HPMC (hydroxypropyl methylcellulose) is a non-ionic cellulose ether that is commonly used as a thickening, water-retention, and adhesion-enhancing agent in various construction materials, including tile adhesives, gypsum, wall putty, and mortar. It is a white or off-white odorless powder that is soluble in water and polar solvents. HPMC is produced by etherifying cellulose, […]
