HPMC cellulose ether Physical property
Appearance and character: white or white like fibrous or granular powder.
Density: 1.39 g / cm3
Solubility: almost insoluble in anhydrous ethanol, ethyl ether and acetone; swelling in cold water to form clarified or slightly cloudy colloidal solution.
Stability: solid is flammable and incompatible with strong oxidant
HPMC cellulose ether application:
1. Architecture industry
A. HPMC is used as water-retaining-agent in all kinds of compo materials, such as mortar, plaster, putty powder and other adhesive materials. It enhances the spread ability and the pump ability, lengthens the operable time of the wet materials.
B. HPMC is used as adhesive for tiles, marbles, plastic ornaments and plaster tone. It also reduces the dosage of cement.
C. The water retention property of HPMC leads the pulp not to dry too quickly, avoids crackings after spreading, and enhances the intensity of the coating.
2. Paint industry
HPMC is used in paint industry as thickening agents, dispersing agents and stabilizers. It has good intermiscibility with water or organic solvents.
3. Printing and ink printing
HPMC is used in printing ink industry as thickening agents, dispersants and stabilizers.
4. Plastic industry
HPMC is used in plastic industry for forming release agents, softeners, lubricants and so on.
5. Others:
HPMC is also widely used in the leather and paper industries, fruit and vegetable fresh-maintaining and textile industry and so on.
Hydroxypropyl Methyl Cellulose(HPMC) is a non-ionic cellulose ether made from natural polymer cellulose and made up through a series chemical processing.
HPMC cellulose ether are the white powder of odorless, tasteless and non-toxic, it can be swelled into clear or slightly muddy colloid solution in cold water. They have properties like thickening, bonding, dispersing, emulsifying, film, suspension, adsorption, gel, surface activity, maintaining water and protective colloid and so on.
Packing, storage and transport:25kg package in woven bag.
Keep dry where good ventilated.
Do not wet, and keep from sunshine when transport.
