HPMC(Hydroxy propyl methyl cellulose)
is a type of nonionic cellulose ether made from natural high molecular materials through a series of chemical processes. With almost all properties of methyl cellulose (MC), it is the auxiliary agent of first choice in the production of top-quality construction materials. To satisfy the requirement of environment protection, Tasong brand product is developed and produced particularly for the construction material industry. With such favorable features as high water retention, good dispersancy, high degree of fineness, nice placeability and convenience to dissolve, it is applicable to the production of innovative construction materials like dry-powder mortar, waterproof putty powder (paste) for indoor and outdoor walls, binding agent, gap filler, interface finishing agent, water paint, self-leveling agent, etc. In the production of construction materials, cellulose ether is an indispensable additive. After HPMC is added, the following properties can be enhanced.
1.
Water Retention
: The water retention will be enhanced, which is helpful with such problems as cement or gypsum construction material drying too fast and poor hardening or cracking due to insufficient hydration.
2.
Operationality
: It can enhance the plasticity of mortar and improve the coating efficiency in construction projects.
3.
Adhesivity
: It can make mortar attach to base material better since the plasticity of mortar is enhanced.
4.
Slip Resistance
: It can prevent slipping problem between mortar and the base material in construction project as a result of its thickening effect.

IV. Physical and Chemical Properties
1. Appearance: HPMC is white or whitish fibrillar/granular and odorless powder
2. Dissolvability: HPMC is dissolvable in cold water and become clear or slightly cloudy liquid cement, but hardly in absolute ethyl alcohol, ethylether or propanone. In addition, HPMC is dissolvable in some organic solvents or some mixed solvents of water and organic solvent.
3. Granularity: Throughput rate: ≥98.5% for 100 mesh and up to 100% for 80 mesh.
4. Apparent Density: 0.30-0.70g/cm3, and density: 1.26-1.31g/cm3.
Main Applications
HPMC may serve as thickening agent, dispersant agent, emulsifying agent or film-forming agent, and its industrialized products may be applicable to the production of daily chemicals, synthetic resin, construction and coating materials.
1. Suspension Polymerization
In the production of synthetic resin such as polyvinyl chloride (PVC), polyvinylidene chloride (PVDC) and other copolymerisate, suspension polymerization is the most used and it requires to keep hydrophobic monomers to suspend in the water. HPMC product has excellent surface activity as a type of water-soluble polymer. In addition, it plays the role of colloidal protectant that it can delay the coacervation of particles. Furthermore, although HPMC is a type of water-soluble polymer, it is somewhat dissolvable in hydrophobic monomers and can enhance the monomer porosity for production of polymerizing particles, thus, it may render polymer good capacity for removal of residual monomers and absorption of plasticizer.
2. It is applicable to the production of following products in the recipe of construction materials.
1) Waterproof putty powder
2) Cement sand mortar
3) Cement base brick/tile and the bonding between tile and base brick
4) Plaster for gypsum board base
5) Cement-based structural plaster.
