Detailed description of the two types of hydroxypropyl methylcellulose HPMC Hydroxypropyl

Detailed description of the two types of hydroxypropyl methylcellulose HPMC Hydroxypropyl methylcellulose can be divided into instant type and hot melt type.

1) HPMC instant product: When cold water is quickly dispersed and disappears in water, because HPMC is only dispersed in water and not really dissolved, the liquid is not viscous. In about 2 minutes, the viscosity of the liquid gradually increased, forming a transparent viscous gel.

2) HPMC hot melt products: In the case of cold water, they can be quickly dispersed in hot water and disappear in the hot water. When the temperature drops to a certain temperature, the viscosity slowly appears until a transparent viscous gel is formed.

All in all, in the production process of HPMC, we select suitable hydroxypropyl methylcellulose HPMC products according to different products and different production processes to maximize production efficiency and commercial benefits. Hot-melt HPMC can only be used in putty powder and mortar. In liquid glue and coating, there will be clumps and cannot be used. Ready-to-use HPMC is widely used, and can be used in putty powder and mortar, as well as liquid glue and paint, without any contraindications.
