Hydroxypropyl Methyl Cellulose (HPMC)

Hydroxypropyl Methyl Cellulose (HPMC) is a non-ionic cellulose ether made from natural renewable polymers such as cotton or wood pulp. It is an odorless, tasteless, non-toxic white powder that forms a transparent sticky solution when dissolved in cold water. When used as construction and daily chemical additives, it is commonly used in tile adhesives, putty, exterior wall insulation materials and washing daily chemical products. Good cellulose ether products should have good thickening, water retention, dispersion, film-forming and other effects.

Tengda is a reliable supplier of cellulose ether with decades of experience in the industry. From purchasing to production, every step of Tengda's researchers will carry out strict detail control.

Features of HPMC

1.SOLUBILITY

Can be dissolved in water, its highest concentration is only determined by the viscosity, the solubility changes with the viscosity, the lower the viscosity, the greater the solubility.

2. NON-IONIC

The product is a non-ionic cellulose ether, and it is not a polyelectrolyte, so it is relatively stable in aqueous solution in the presence of metal salts or organic electrolytes, but excessive addition of electrolytes can cause gelation and precipitation

3. SURFACE ACTIVITY

Due to the active function of the aqueous solution, it can be used as a colloidal protective agent, emulsifier and dispersant

4. THERMAL GELS

When the product aqueous solution is heated to a certain temperature, it becomes opaque and the gel forms a precipitate. However, when it is continuously cooled, it returns to the original solution state. The temperature at which this gelation and precipitation occurs mainly depends on their lubricants and suspending agents. Protective colloid. Emulsifier, etc.

5. FILM FORMATION

Can form a transparent, tough and flexible film with good oil resistance and water resistance

6. MILDEW RESISTANCE

Has relatively good anti-fungal ability. Good viscosity stability during long-term storage.

Application scenarios and advantages

HPMC is applied in tile adhesive

HPMC (hydroxypropyl methylcellulose) is a water-soluble polymer with excellent viscosity, fluidity, dispersion and stability. It is widely used in building materials, especially as an additive for ceramic tile adhesives.
