What are the factors that affect the viscosity of hydroxypropyl methylcellulose

Hydroxypropylmethylcellulose

Hydroxypropyl methylcellulose has a wide range of applications and has a great relationship with viscosity. Different applications of hydroxypropyl methyl cellulose require different viscosities.

Therefore, when using their products, we must first understand their viscosity, but the viscosity of hydroxypropyl methylcellulose is affect by many factors.
If stored carelessly, adhesion failure may result.

So what factors are related to the viscosity of hydroxypropyl methylcellulose? Let me introduce it briefly.

Generally, the viscosity of hydroxypropyl methylcellulose is affected by:

1. The higher the degree of polymerization of cellulose ether, the larger the molecular weight of the aqueous solution and the higher the viscosity;

2. The higher the amount (or concentration) of cellulose ether, the higher the viscosity of the aqueous solution. It affects the properties of mortar and concrete;

3. As with most liquids, the viscosity of cellulose ether solution decreases with increasing temperature, and as the concentration of cellulose ether increases, the effect of temperature also increases;

Generally, when observing from the above points, when controlling the viscosity of hydroxypropyl methylcellulose, it is necessary to check and use hydroxypropyl methyl cellulose multiple times during storage.
