Now, viscosity is generally used to distinguish hydroxypropyl methyl cellulose, but for some special environments and special industries, the viscosity of products is not enough. Here is a brief introduction of hydroxypropyl methyl cellulose […]
Read MoreHPMC manufacturer-What Are the Main Functions of HPMC in A Dry Mix Mortar? Hydroxypropyl methylcellulose is one of the key ingredients in dry-mix mortars because of its ability to influence key dry-mix properties such as water retention, curing, workability, rheology, and thixotropy. 1. Water Retention The excellent water retention of hydroxypropyl methylcellulose gives the cement […]
