Hydroxy propyl methyl cellulose (HPMC) is a non-ionic cellulose ether used in various industries including construction, coatings, and food. It features properties such as thickening, water retention, and binding, and is soluble in water and polar organic solvents. The production of HPMC involves refined cotton and sodium hydroxide, and its cost is significantly influenced by the price of raw materials, primarily refined cotton.

1. Chemical Name: Hydroxy Propyl Methyl Cellulose
CAS NO.: 9004-65-3 Abbreviation: HPMC MHPC
Industries: Construction, Coating, Paints, Detergent
HPMC is one of cellulose ethers, is short for hydroxypropyl methyl
cellulose. It is also called hypromellose,or 2-hydroxypropyl methyl
cellulose.
Material: High purlty Refined cotton
HPMC is a type of non-ionic cellulose ether, white powder
appearance, odorless and tasteless, soluble in water and most
polar organic solvents. Its water solution has a surface activity, high
transparency, stable performance. HPMC has a thermal gel
properties, after heating, the product solution formed the gel
precipitation, dissolving after cooling. Different specifications
products have different gel temperature. Solubility changes with
viscosity's difference. The lower viscosity, the higher solubility,
different specifications HPMC have difference in properties,
dissolving HPMC in water won't be affected by PH value.
Granularity: 100mesh, over 99% passing rate, Bulk Density:
0.25-0.70g(usu. 0.5g or so), Proportion: 1.26-1.31, Color
Temperature: 190-200℃

2. Carbonization Temperature: 280-300℃,Surface Tension:
42-56dyn/cm
With the increase of Methoxyl, HPMC's gel point decreases, the
rise of water solubility and surface activity. HPMC has the features
of thickening, salt removing, low ash content, fine film-forming
properties. and wide range of anti-ether, dispersion, and adhesion
properties.
Properties:
1.Enhances water retention--improved water retenion can
protectcement and plaster against poor solidification and cracking
due to speedy drying and inefficient mixing with water.
2.Workablilty--mortar plasticizing quality can be improved, which in
turn will improved the workability of painting and working efficiency.
3.Binding--Due to increased plasticizing quality, mortar can be a
better binde.
4.Slipping resistance--Due to the thickening action of Cellulose
Ether,the slipping phenomena of mortar from substance to be
bound can be prevented more efficiently.

3. Package:
A. Standard Packing: In 25kg paper bags inner with PE bags
B. Big Bag or other special packages are possible on request.
Safety:
This product is non-toxic and has no irritation to skin and mucous
membrane.
Product Transportation and Storage: Prevent from sun, rain and
moisture and keep it in a sealed dry place.
Hydroxypropyl methylcellulose is a nonionic cellulose ether with a
white powder appearance, odorless and tasteless, soluble in water
and most polar organic solvents, proper ratio of ethanol/water,
propanol/water, dichloro Ethane and other insoluble in ether,
acetone, anhydrous ethanol.
Hpmc , methyl cellulose can be used in building materials, coatings
industry, synthetic resin, ceramic industry, medicine, food, textile,
agriculture, household chemicals, etc.
It’s outstanding functions:
Thermal gelation;
Effective binding;
Thickening and stabilizing;
Water retention and softness improving；

4. The production process of Hydroxypropyl Methylcellulose (HPMC)
Reaction: Rcell – OH+ NaOH+ CH3Cl +CH2OCHCH3
→Rcell – O – CH2OHCHCH3 + NaCl + H2O
production process of HPMC
Raw materials: refined cotton, sodium hydroxide, chloromethane,
and epoxypropane.
Approximate raw material consumption for 1mt HPMC
List Spec
Consumption
Refined cotton Water≤6% 0.93MT

5. Sodium hydroxide ≥50 % 1.15MT
Methyl chloride ≥99 % 0.75MT
Propylene oxide ≥99 % 0.25MT
All factors affecting product cost
■Raw materials
The pricing of refining cotton, sodium hydroxide, methyl chloride,
and propylene oxide will have a big influence on product cost.
Among these raw materials, the price of refined cotton is the key
factor which determines the production cost of HPMC. From the
following chart, we will find the cotton production by country
worldwide in 2017/2018 (in 1,000 metric tons)
With around 100,000 farmers cultivating cotton, China is the
second biggest cotton producing country. Therefore, Chinese
HPMC has very big competitive advantages on production cost.
