Milestone has been producing Hydroxypropyl Methyl Cellulose HPMC for more than 20 years. When the factory was first built, it was a small factory that produced 1 ton per day. Now it has two factories with a production capacity of 30 tons per day.

Hydroxypropyl Methyl Cellulose HPMC production method: Hydroxypropyl Methyl Cellulose HPMC, also known as hypromellose, cellulose hydroxypropyl methyl ether, is made of highly pure cotton cellulose as raw material, treated with lye at 35-40℃30 Minutes, squeeze, pulverize the cellulose, and properly age at 35°C to make the obtained alkali fiber average polymerization degree within the required range. Put the alkali fiber into the etherification kettle, and etherify at 50-80°C for 5h, the pressure is about 1.8MPa. Then wash the material in hot water at 90°C to increase the volume, and then dewater it in a centrifuge, and then repeatedly wash to neutrality.
