Import Hydroxypropyl Methyl Cellulose — Buy in wholesale FOB from Supplier in China

Hydroxypropyl methyl cellulose (HPMC) is a kind of odorless, tasteless and non-toxic white powder,

1. Appearance: white or off white powder, odorless and tasteless.

2. Particle size: the passing rate of 100 mesh is greater than 98.5%; The passing rate of 80 meshes is greater than 100%.

3. Carbonization temperature: 280-300 â??.

4. Apparent density: 0.25-0.70g/ (usually about 0.5g/), specific gravity: 1.26-1.31.

5. Discoloration temperature: 190-200 â??.

6. Surface tension: 42-56dyn/cm for 20% aqueous solution. Purpose: As thickener, stabilizer, emulsifier, excipient, water retaining agent, film-forming agent, etc. in the production of coatings, building materials, paint removers, agricultural chemicals, inks, textile printing and dyeing, ceramics, papermaking, cosmetics and other products. The application in synthetic resin can make the obtained products have the characteristics of regular particles, looseness, appropriate specific gravity, excellent processing performance, etc., thus basically replacing gelatin and polyvinyl alcohol as dispersants. In addition, in the construction process of the construction industry, it is mainly used in mechanized construction such as wall building, plaster finishing, caulking, etc; Especially in decorative construction, it is used for pasting ceramic tiles, marble and plastic decoration, with high pasting strength, and can also reduce the amount of cement. Used as a thickener in the coating industry, it can make the layer bright and delicate, do not remove powder, and improve the leveling performance. Function: It can thicken the fresh mortar to have a certain wet viscosity and prevent segregation. (thickening) Water retention is also the most important characteristic, which helps to maintain the amount of free water in the mortar, so that the cementitious material has more time to hydrate after the mortar construction. (water retention) It has air entrainment, which can introduce uniform and fine bubbles to improve the workability of mortar. Performance:

1. It is easy to mix with dry powder formula.

2. It has the characteristics of cold water dispersion.

3. The solid particles are effectively suspended to make the mixture more smooth and uniform. Mix:

1. The dry mixed formula containing cellulose ether can be easily mixed with water.

2. Get the required consistency quickly.

3. Cellulose ether dissolves more quickly and has no lumps. be used as: Waterproof putty for interior and exterior walls External wall insulation mortar Gypsum plaster and gypsum products Cement based plastering mortar and masonry mortar Plate joint filler Tile adhesive Self leveling ground material Water based coatings and paint removers Extruded concrete sheet
