HPMC For Joint Filler
Hydroxypropyl Methyl Cellulose HPMC
Hydroxypropyl methylcellulose (HPMC) CAS9004-65-3 is a non-ionic cellulose prepared from natural polymer materials through a series of chemical processing. It contains methylcellulose (MC) with almost all properties and is your first choice for the production of high-quality building materials additives. In order to meet the needs of environmental protection, our HPMC powders have high water retention, dispersibility, good fineness, good workability, and easy-to-use dissolution characteristics.
HPMC hydroxypropyl methyl cellulose is suitable for building dry powder mortar, internal and external wall putty powder (paste), adhesives, caulking agents, joint cover, interface agents, coatings, and self-leveling agents for new building materials additives.

Joint Filler HPMC PROPERTIES:
* Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh.
* Charring temperature: 280-300℃.
* Bulk density: 0.25-0.70 g/cm3 (Usually around 0.5 g/cm3 )
* Real specific gravity: 1.26-1.31.
* Browning temperature: 190-200℃.
* Surface tension: (2% water solution) 42-56dyn.cm.
* Properties: Dissolved in water and some organic solvent such as ethanol. propyl alcohol. ethylene chloride, the water solution is of surface activity. It is a nonionic surface active agent. Gelation temperature is different for different grades. For example, among 60RT Hydroxypropyl Methylcellulose, 60 is gelation temperature, Namely, 2% water solution will form gelation at 60%.
