How to choose HPMC from water retention!
The water retention from Hydroxypropyl Methyl Cellulose is one of the important properties of Hydroxypropyl Methyl Cellulose. Factors such as air temperature, temperature and wind pressure speed will affect the volatilization rate of water in cement mortar and gypsum-based products. Therefore, in...Read more -
Application of auxiliary material hydroxypropyl cellulose in solid preparation
Hydroxypropyl cellulose, a pharmaceutical excipient, is divided into low-substituted hydroxypropyl cellulose (L-HPC) and high-substituted hydroxypropyl cellulose (H-HPC) according to the content of its substituent hydroxypropoxy. L-HPC swells into a colloidal solution in water, has the properties...Read more -

The rubber i...Read more -
Comparison of the types and advantages and disadvantages of thickeners in water-based paints!
Coating additives are used in a small amount in coatings, but they can significantly improve the performance of coatings, and have become an indispensable part of coatings. Thickener is a kind of rheological additive, which can not only thicken the coating and prevent sagging during construction,...Read more -
How should the thickener in water-based paint be added?
Today we will focus on how to add specific types of thickeners. The types of commonly used thickeners are mainly inorganic, cellulose, acrylic, and polyurethane. Inorganic Inorganic materials are mainly bentonite, fumed silicon, etc., which are generally added to the slurry for grinding, because ...Read more -
The role of cellulose ether in ready-mixed mortar
In ready-mixed mortar, the addition amount of cellulose ether is very low, but it can significantly improve the performance of wet mortar, and it is a main additive that affects the construction performance of mortar. Reasonable selection of cellulose ethers of different varieties, different visc...Read more -

Effect of Hydroxypropyl Methyl Cellulose Ether (HPMC) on the Water Holding Capacity of Powder
Hydroxypropyl methylcellulose (HPMC) mainly plays the role of water retention, thickening and improving construction performance in cement, gypsum and other powder materials. Excellent water retention performance can effectively prevent the powder from drying and cracking due to excessive water l...Read more -
Application example of CMC in acidic milk drink
1. Theoretical basis It can be seen from the structural formula that the hydrogen (Na+) on CMC is very easy to dissociate in aqueous solution (generally exists in the form of sodium salt), so CMC exists in the form of anion in aqueous solution, that is, it has a negative charge and is amphoteric....Read more
