China's leading manufacturer of Cellulose Ether, offering Plaster Retarder solutions.
As a key functional additive, Cellulose Ether improves water retention, thickening, workability, open time, and adhesion performance, making it essential in modern building material formulations.
We supply stable quality HPMC (Hydroxypropyl Methyl Cellulose) and MHEC (Methyl Hydroxyethyl Cellulose) to distributors, mortar factories, and construction chemical manufacturers worldwide.
Cellulose Ether is a group of chemically modified cellulose derivatives produced from natural plant fibers. Through etherification, cellulose becomes water-soluble and gains valuable thickening and water-retention properties.
In construction applications, cellulose ether functions primarily as:
Common construction-grade cellulose ethers include:
Among these, HPMC and MHEC are the most widely used in dry mix mortar and cement-based systems.
Below are typical parameters for construction-grade cellulose ether:
| Item | Standard Specification |
|---|---|
| Appearance | White or off-white powder |
| Methoxy / Hydroxypropyl Content | Based on grade |
| Viscosity (2% solution) | 5,000 – 200,000 mPa.s |
| Moisture Content | ≤ 5% |
| pH Value | 6.0 – 8.0 |
| Gel Temperature | 55–75°C |
| Ash Content | ≤ 5% |
| Recommended Dosage | 0.1% – 0.6% |
Note: Product specifications may vary according to different grades and application requirements. Laboratory testing is recommended before commercial production.
By choosing right products, you can optimize crack resistance, toughness, and durability across a wide range of concrete projects.
One of the most important properties of cellulose ether is its ability to retain water in cement and gypsum systems. This prevents premature drying and ensures proper hydration of cement.
Cellulose ether enhances the smoothness and consistency of mortar and putty, making mixing and application easier.
In tile adhesive and plaster applications, cellulose ether increases open time, allowing more flexibility during installation and adjustments.
It improves bonding strength by maintaining moisture balance and supporting cement hydration.
In vertical applications such as tile adhesive or wall plaster, cellulose ether improves anti-slip and anti-sagging performance.
It provides stable viscosity control and rheological behavior in dry mix formulations.
