How Redispersible Polymer Powders Are Produced
Redispersible polymer powders (RDP) are free-flowing, dry powders obtained from water-based polymer dispersions. They can be easily rehydrated in water to form a stable dispersion with properties similar to the original liquid polymer. This makes RDPs widely used in dry-mix building materials suc...Read more -
What is the difference between HEC and HPMC?
HEC (hydroxyethyl cellulose) and HPMC (hydroxypropyl methyl cellulose) are both non-ionic cellulose ether chemicals widely used in construction, coatings, daily chemicals, food, and pharmaceuticals. However, they differ significantly in their chemical structure, performance characteristics, and a...Read more -
Definition and Properties of Methylcellulose
Methylcellulose (MC) is a nonionic cellulose ether made from natural cellulose via a methylation process. It exhibits excellent solubility, thickening, film-forming, and lubricating properties, forming a transparent colloidal solution in water. Being non-toxic, odorless, and highly stable, MC is ...Read more -
HPMC Usage in Construction
Hydroxypropyl methylcellulose (HPMC) is an indispensable polymer additive in modern dry-mix mortar systems. It retains water, thickens the mortar, and improves workability. Properly controlling the HPMC dosage is crucial to the performance of the mortar or adhesive. 1. Main Applications of HPMC ...Read more -
