Hydroxy Propyl Methyl Cellulose

Hydroxy Propyl Methyl Cellulose , also shortened to HPMC, is a variety of non-ionic cellulose mixed ethers. It is a semi-synthetic, inactive, elastic polymer that is often used as a lubricant in ophthalmology, or as an excipient or excipient in oral medications. It is commonly found in various types of products. As a food additive, propyl methylcellulose can play the following roles: emulsifier, thickener, suspending agent and substitute for animal gelatin..

HPMC is widely used in building materials, coatings, synthetic resins, ceramics, pharmaceuticals, food, textiles, agriculture, cosmetics, tobacco and other industries. It can be divided into: construction grade, food grade and pharmaceutical grade according to its use. At present, most domestic products are of construction grade. In construction grade, a large amount of putty powder is used. About 90% is used to make putty powder, and the rest is used to make cement mortar and glue.

  • Enhance water retention and improve the phenomenon of poor hardening and cracking caused by over-drying of cement and gypsum building materials and insufficient water.
  • Increases the plasticity of mortar, improves the industrial properties of steamed bun construction, and improves work efficiency.
  • Still has good thickening properties at low surfactant (2.596).
  • Directly reduce the usage of sulfonic acid and AES, thickening without affecting the sea cleaning effect.
  • Sealed packaging, not easy to leak, convenient transportation, easy to store.

4. Package and storage:
Hydroxy Propyl Methyl Cellulose are package in 25kg multilayer paper bags with polyethylene intermediate layer.
It could be stored well for a long time by avoiding directly to contract with moist environment.
