Hydroxypropyl Methyl Cellulose HPMC

HPMC is a highly pure cotton cellulose as raw material, under alkaline conditions by special etherification and preparation.White or whitish powder.HPMC decreases with the decrease of methoxide content, increase of gel point, decrease of water solubility and decrease of surface activity.
HPMC has thickening ability, salt resistance, low ash powder, pH stability, water retention, dimensional stability, excellent film forming, and a wide range of enzyme resistance, dispersion and adhesion.

HPMC is widely used in building materials, coating, synthetic resin, ceramics, medicine, food, textile, agriculture, cosmetics, tobacco and other industries.HPMC by use can be divided into: construction grade, food grade and medical grade.At present homebrew is building level mostly, in building level, be bored with child pink dosage is very big, about 90% is to use be bored with child pink, the rest is to use make cement mortar and glue
 

Construction industry

1.Used as a binder in plaster, gypsum, putty powder, mortar or other building materials to improve processability and extend operating time. Prevents the slurry from drying and cracking too quickly after spraying, and the strength is enhanced after hardening.
2.Used as a tackifier for tiles, marble and plastic finishes.
Ceramic industry
Ceramic industry: widely used as a binder in the manufacture of ceramic products.
Coating industry
1.Used as a thickener, dispersant and stabilizer in the coatings industry. Good compatibility with water or organic solvents.
2.Used as paint stripper, dispersion coating, wall coating, polymerization aid.


we established in in 2008 , we specialize in manfacture hydroxypropyl methylcellulose (HPMC) and Redispersible Polymer Powder(RDP) for many years , our company covers an area of 120 acres, now has 280 employees, including 28 senior technicians.
