Hydroxypropyl Methyl Cellulose (HPMC) Used for Cement base plaster

Provides lubricity
We gives the modified mortar its lubricity. This lubrication effect reduces the friction and thus reduces the extrusion temperature, which in turn reduces the water evaporation, better allowing the extruded element to complete the hydration process.

Reduces tool wear
In addition to lowering the inter-particle friction force,we also lowers the friction and abrasive force against the extrusion tools, leading to less tool wear, prolonging its useful life, some times even doubl ing the useful life, thus reducing one major cost.

Increases water demand
Unmodified true zero-slump extrusion mix contains very l ittle extra water needed for hydration to complete. When a portion of this water is evaporated due to heat produced during extrusion process, hydration cannot complete properly. We can provide the zero-slump even at elevated water levels, without sacrificing strength, which normal ly happens with a higher water:cement ratio, thus al lowing the hydration to actually complete.

Improves water retention
The compression force and friction force tend to heat up the extrusion mix and cause water to evaporate, leaving little water for hydration to occur. We can retain the water effectively even at elevated temperature to allow hydration to complete.

Provides excellent strength
We can give the freshly extruded material excellent green strength, so that they can be handled and moved without much worry of slumping or shape loss.
