hydroxypropyl methylcellulose (hpmc) powder uses in detergent

Hypropyl methylcellulose (hypropyl mellose), also known as hydroxypropyl methylcellulose, is a kind of non-ionic cellulose mixed ether.

PHYSICAL AND CHEMICAL PROPERTIES:

Viscosity : 400-200000 mpas (can be customized)

* Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh.

* Charring temperature: 280-300℃.

* Bulk density: 0.25-0.70 g/cm3 (Usually around 0.5 g/cm3 )

* Real specific gravity: 1.26-1.31.

* Browning temperature: 190-200℃.

* Surface tension: (2% water solution) 42-56dyn.cm.

* Properties: Dissolved in water and some organic solvent such as ethanol. propyl alcohol. ethylene chloride, the water solution is of surface activity. It is a nonionic surface active agent. Gelation temperature is different for different grades. For example, among 60RT Hydroxypropyl Methylcellulose, 60 is gelation temperature, Namely, 2% water solution will form gelation at 60%.

Dissolution method

1. All models can be added to the material by dry mixing method.

2, need to be directly added to the normal temperature aqueous solution, the best use of cold water dispersal type, after adding generally in 10-90 minutes to thicken.

3, ordinary model first with hot water stir dispersion, add cold water stir cooling can be dissolved.
