CAS No.:9004-65-3

Hydroxypropyl Methyl Cellulose other names Hypromellose; Hydroxypropyl methylcellulose; HPMC; E464 is a non-ionic cellulose ether in the shape of white powder, odorless and tasteless, with many fields of application.

 

Hydroxypropyl Methyl Cellulose (HPMC) is also named as MHPC, are types of non-ionic cellulose ether, which are a powder of white to off-white color, that function as a thickener, binder, film-former, surfactant, protective colloid, lubricant, emulsifier, and suspension and water retention aid. In addition, these types of cellulose ethers exhibit properties of thermal gelation, metabolic inertness, enzyme resistance, low odor and taste, and pH stability. HPMC are widely used in construction,pharmaceutical,food,cosmetic,detergent,paints,textiles etc.We can provide the general grade HPMC, we also designed the modified HPMC according to customer requirements. After modified, we can get the product which have long open time, good anti-sagging,good workability etc.

 

 

HPMC main performance

HPMC main applications

 

 

HPMC for Tile Adhesive

1,Good water retention: prolonged opening time will make tiling more efficient.

2,Improved adhesion and sliding resistance: especially for heavy tiles.

3,Better workability: lubricity and plasticity of plaster is ensured, mortar can be applied easier and quicker.

 

Cement Plaster / Dry mix mortar

1,Easy dry mix formula due to cold water solubility: lump formation can be easily avoided, ideal for heavy tiles.

2,Good water retention: prevention of fluid loss to the substrates, the appropriate water content is kept in mixture which guarantees longer concreting time.

3,Increased water demand: increased open time, expanded spry area and more economical formulation.

4,Easier spreading and improved sagging resistance due to improved consistency.

 

 

 

HPMC for Wall putty

 

1,Water retention: maximized water content in slurry.

2,Anti-sagging: when spreading a thicker coat corrugation can be avoided.

3,Increased mortar yield: depending on the weight of the dry mixture and appropriate formulation ,HPMC can increase the mortar volume.

 

HPMC for Exterior Insulation and Finish System ( EIFS )

 

1,Improved adhesion.

2,Good wetting ability for EPS board and substrate.

3,Reduced air entrancement and water uptake.

 

HPMC for Self-leveling

 

1,Protection from water exudation and material sedimentation.

2,No effect on slurry fluidity with low viscosity

 

 

HPMC for Crack Filler

 

1,Better workability: proper thickness and plasticity.

2,Water retention ensures prolonged work time.

3,Sag resistance: improved mortar bonding ability.
