Composition and chemical structure:
HPMC is white powder or granule made from highly pure cotton - cellulose by reaction of etherification. HPMC is characterized by water solubility, water retention, nonionic, stability of the PH value, surface activity, temperature reversible gelling properties, thickening property, film formability, lubrication property etc.,without any organs of animals, fat and other bioactive constituents.

white or off-white fibrous or granular powder: odorless, tasteless
In the course of construction, HPMC used to build by laying bricks or stones wall, plaster, caulking, paste tile, marble, plastic decoration, paste with high intensity, can reduce the dosage of cement. Sealing used in stucco gypsum, adhesive plaster, gypsum, water resistant putty can significantly improve the water retention, adhesive strength, etc.
Physical and chemical performance
1). The appearance: white or white powder, odorless and tasteless.
2). Particle size: 100 order by the rate of more than 98.5%; 80 mesh through rate in 100%.
3). The carbonization temperature: 280-300℃.
4). The apparent density:0.25-0.70g/ (usually 0.5g/). Specific gravity 1.26-1.31.
5). Temperature: 190-200℃
6). Spontaneous combustion temperature of about 360℃.
7). The surface tension of aqueous solution of 42-56dyn/cm:20%.
8). HPMC with methoxyl content decreases, the gel point elevation, dissolved in water decline, surface activity also decreased.
9).The solubility: soluble in water and organic solvents, such as an appropriate proportion of ethanol/water, isopropanol/water, two chlorine ethane and. Aqueous solution with surfactant, high transparency, stable performance. Products of different specifications in different gel temperalures, this is HPMC thermal gelation properties. The solubility increases with the viscosity and viscosity change, the lower the solubility, higher, different specifications of the HPMC properties have some differences. HPMC solubility in water is not affected by Ph value influence.
