  Specification  

  Viscosity Specifications  

  Production Process  

As HPMC manufacturer, our HPMC production process is as follows:

Hydroxypropyl methyl cellulose (HPMC) is made from refined cotton after being pulverized, and then alkalized with sodium hydroxide (liquid caustic soda) solution, and then monochloromethane + propylene oxide is added for etherification to form crude HPMC , After neutralization (pH adjustment), filter press, drying, crushing and sieving, a pure HPMC product of certain fineness is obtained. The finished product has a slight smell, the smell of methane.

  Application field  

• Mortar/Concrete/EIFS/ETICS

• Tile adhesive

• Renders/Plasters/Skim Coat

• Painting

• Ceramic Extrusion

• Self leveling

• AAC Block

• PVC

• Fire Retardant Paint

• Detergent / Hand Sanitizer / Laundry Liquid

  Packaging, storage and transportation  

HPMC can be packed in paper-plastic composite bags lined with polyethylene plastic bags, cardboard drums or plastic coated, etc., each with a net weight of 25KG. During storage and transportation, it should be protected from sun and rain, fire and moisture.

Hebei Yida Cellulose Co., Ltd. is a HPMC manufacturer with 16 years of production experience. It produces HPMC for construction and daily chemicals. The annual output of HPMC powder is 30,000 tons. Serving more than 500 customers in more than 40 countries.

Q1: How does HPMC contribute to the workability of mortar and plaster mixes?

A1: HPMC enhances the workability of mortar and plaster mixes by improving their viscosity and flow properties. It allows for easier application, reduces the need for excessive water addition, and prevents segregation of components during mixing and application.

Q2: Can HPMC be used to improve the adhesion of tile adhesives to various substrates?

A2: Yes, HPMC is often incorporated into tile adhesives to improve their adhesion to various substrates such as concrete, plaster, and ceramic tiles. It acts as a binder, enhancing the bond strength and reducing the risk of tile failure over time.

Q3: How does HPMC affect the water retention capabilities of plaster and mortar?

A3: HPMC helps to improve the water retention capabilities of plaster and mortar by forming a hydrophilic film around the particles. This film slows down the evaporation of water during curing, allowing for more uniform hydration and stronger, more durable end products.

Q4: Can HPMC be used to modify the setting time of gypsum-based products like wallboard?

A4: Yes, HPMC can be used to adjust the setting time of gypsum-based products like wallboard. By controlling the hydration rate of the gypsum, HPMC can either delay or accelerate the setting process, depending on the desired application and performance requirements.

Q5: How does HPMC contribute to the performance of detergents, dishwasher detergents, and laundry detergents?

A5: In detergents, dishwasher detergents, and laundry detergents, HPMC serves as a thickening agent and stabilizer. It helps to suspend and uniformly distribute active ingredients and particles throughout the liquid, ensuring consistent cleaning performance. Additionally, HPMC can improve the viscosity of the product, making it easier to pour and measure. Its film-forming properties can also aid in the removal of dirt, grease, and stains, enhancing the overall cleaning power of the detergent. Furthermore, HPMC is compatible with a wide range of surfactants and other cleaning ingredients, allowing for the formulation of effective and gentle cleaning solutions.
