hpmc manufacturer-There are several types of hydroxypropyl methylcellulose (HPMC). What are the differences in their uses? HPMC can be divided into instant type and hot-melt type. Instant-dissolve products are quickly dispersed in cold water and disappear in the water. At this time, the liquid has no viscosity, because HPMC is only dispersed in water without real dissolution.About 2 minutes, the viscosity of the liquid gradually increased, forming a transparent viscous colloid.The hot-melt product, when it meets with cold water, it can quickly disperse in hot water and disappear in hot water. When the temperature drops to a certain temperature, the viscosity slowly appears until a transparent viscous colloid is formed.Hot-melt type can only be used in putty powder and mortar. In liquid glue and paint, clumping occurs and cannot be used.The instant type has a wider range of applications. It can be used in putty powder and mortar, as well as in liquid glue and paint. There is no contraindication.
