Methylcellulose is a non-ionic cellulose ether, which is produced by etherification by introducing methyl groups into cellulose.
Methylcellulose is a cellulose methyl ether. White or light yellow or light gray small particles, filamentous or powder. Odorless and tasteless, with approximately 27% to 32% of hydroxyl groups present in the form of methoxy groups. Different levels of methyl cellulose have different degrees of polymerization, ranging from 50 to 1000; And its molecular weight (average) ranges from 10000 to 22000 Da, and its degree of substitution is defined as the average number of methoxy groups, which are connected to each glucose anhydride unit on the chain.

Physical and Chemical Properties
1,Appearance: White or quasi-white fibrous or granular powder, odorless and tasteless.
2,Solution: Almost insoluble in ethanol, ether, chloroform (1: 1) in the mixture can form a clear or suspended viscous solution. In 80-90 ºC hot water rapid swelling, cooling after rapid dissolution, water dissolution at room temperature is quite stable, high temperature gel, It undergoes a reversible transition from gel to dissolution after heating and cooling.
3,Characteristics: Excellent wettability, dispersion, adhesion, thickening, emulsifying, water-holding and film-forming, and oil impermeability. The film has excellent toughness, flexibility and transparency. Because it is non-ionic, it can be compatible with other emulsifiers, but it is easy to be salted out and the solution is stable in the range of pH 2-12.
4,Density: 1.3g/cm;Apparent density: 0.25-0.7 g/cm³.
5,discoloration temperature: 190-200ºC.
6,Carbonization temperature: 225-230ºC.
7,Surface tension: 47-53 dyn/cn.
Packaging, storage and transportation precautions:
1,Points for attention in storage and transportation:Avoid the sun and rain,moistureproof.
2,Packing: Round cardboard drum for this product(Inner bag lined with medicinal polyethylene film)Encapsulation.
3,Net weight per unit:12.5kg or 15kg.
THE EFFECT AND APPLICATION
Hpmc for Tile AdhesiveWelcel
HPMC can ensure the smooth construction ofdifferent types of tiles on different base surfaces , likewall tile adhesive floor tile adhesive etc Welcel HPMCprovide tile adhesive with excellent water retentionworkability , and sag resistance , and it helps to increaseadhesion strength and open time
Hpmc for Putty Powder
Excellent water retention for longer applicationtime and improved work efficiency . High lubricity ,making the construction easier and smoother . Itprovides a fine and even texture , making thesurface of the putty smoother . High viscosity forbetter adhesion of the putty to the wall
Hpmc for plastics
Cellulose plastic is one of the strongest and toughest plastics among thermoplastic materials, with advantages such as good luster, transparency, hardness, mechanical strength, and dimensional stability. It has excellent heat resistance, electrical insulation, weather resistance, chemical properties, etc.
Hpmc for coatings
HPMC has a thickening effect, which can significantly improve the construction performance and effect, increase the adhesion of the coating, improve the viscosity and rheological properties of the coating during construction, and enhance the feel of the paint film.
Hpmc for Ceramics
Sodium carboxymethyl cellulose CMC is added in ceramic production, mainly as an excipient, plasticizer, and reinforcing agent for billets; The bottom and top glazes used for ceramic tiles can keep the glaze body in a stable and dispersed state; The main application for printing glaze is its thickening, bonding, and dispersion properties.
Hpmc for Self Leveling Mortar
HPMC ensuring the flow of self-levelingmortar Contributes to the formation of a smoothsurface Reduced shrinkage and increasedload-bearing capacity Improve the adhesionand cohesion of self-leveling mortar to thesubstrate
