Hydroxypropyl methylcellulose HPMC gel temperature problem

December 6, 2021by admin0

Regarding the gel temperature of hydroxypropyl methyl cellulose HPMC, many users seldom pay attention to the problem of hydroxypropyl methyl cellulose gel temperature. Nowadays, hydroxypropyl methyl cellulose is generally distinguished by viscosity, but for For some special environments and special industries, it is not enough to reflect the viscosity of the product. The following briefly introduces the gel temperature of hydroxypropyl methylcellulose.

The amount of methoxy group is directly related to the degree of cellulose mashing. The content of methoxy group can be adjusted by controlling the formula, reaction temperature and reaction time. At the same time, the degree of distillation affects the degree of substitution of hydroxyethyl or hydroxypropyl. Therefore, the water retention capacity of cellulose ethers with high gel temperature is generally poor. This production process needs to be explored, so it is not that the methoxyl content is low, the production cost of cellulose ether is low, on the contrary, its price will be higher.

Gel temperature is determined by methoxy, and water retention is determined by hydroxypropoxy. There are only three replaceable groups on cellulose. Find your suitable use temperature, suitable water retention, and then determine the type of cellulose.
