MelaColl™ HPMC series have different viscosity and properties. HPMC is a versatile chemical addictive. Its uses include three ways: construction, daily chemical, food, and pharmacy. In this article, we will talk about Melacoll HPMC grades and uses.
MelaColl™ HPMC’s raw material is refined cotton. The refined cotton endows HPMC with good thickening properties. This is twice that of ordinary people. So it ensures Melacoll HPMC‘s viscosity is higher than DOW or Ashland and Lotte.
Melacoll HPMC manufacturing process is through etherification between propylene oxide, Chloromethane, and another chemical. Melacoll provides a complete supply chain. Its headquarter is in Dallas, Us. The US lab continues to innovate and research new products. We have many experienced R & D personnel. Besides, keep pace with market demand. Put the customer's opinion first.
Our customers are mainly engaged in the construction industry. Like tile adhesive, and wall putty. joint compound, Melacoll HPMC will play a good function. Learn more about Melacoll HPMC grades and uses that can ensure produce good use effects. We have another blog with some questions about cellulose ether and RDP grades from our customs.
Of course, Melacoll continues to upgrade formulas, like tile adhesive formula or wall putty formula. Adopt different HPMC grades to pursue application tests. Using this way to test Melacoll HPMC quality. There are so many HPMC grades in Melacoll. This article mainly focuses on MP 400, MP 20000, MP 45000, and MP 70000.
1.MELACOLL HPMC GRADES AND USES
-
MelaColl™ MP 400
MelaColl™ MP400 is a non-ionic, water-soluble cellulose ether. Its viscosity is low, but it can provide good correction and fluidity. This feature is very practical for self-leveling. Self-leveling mortar is the free flow of cement slurry according to the height of the terrain to achieve a high leveling effect.
| Appearance: | white or off-white powder |
| Moisture: | ≤5 % |
| Ash: | ≤5 % |
| Methoxy content: | 19-24 % |
| Hydroxypropyl content: | 4-12 % |
| PH value: | 6-8 |
| Particle size: | 99% pass 80 mesh |
| Viscosity: | 300-500 mPa.s (Brookfield RV, 2%) |
| Delayed solubility: | No |
| Final consistency: | Low |
| Sag resistance: | Low |
MelaColl™ MP 400 utilizes self-leveling to have the following advantages:
Ensure the fluidity of self-leveling mortar
Form a smooth surface
Reduce shrinkage and increase load-bearing capacity
Improve the adhesion between self-leveling mortar and base

MelaColl™ MP 45000
MelaColl™ MP 45000 is a non-delayed dissolving hydroxypropyl methylcellulose. After dissolving in water, it plays a role in various properties. Wide range of applications, including tile adhesives, putty, fillers, insulation systems, gypsum base, etc. This requires him to have moderate sag resistance and thickening properties. The viscosity range of this product is between 40000-55000.
| Appearance: | white or off-white powder |
| Moisture: | ≤5 % |
| Ash: | ≤5 % |
| Methoxy content: | 19-24 % |
| Hydroxypropyl content: | 4-12 % |
| pH value: | 6-8 |
| Particle size: | 99% pass 80 mesh |
| Viscosity: | 40,000-55,000 mPa.s (Brookfield RV, 2%) |
| Delayed solubility: | No |
| Final consistency: | Moderate |
| Sag resistance: | Moderate |
| Thickening effect: | Moderate |
This product has the following advantages:
Enhance the thickening effect
Improve adhesion. When used in tile adhesive, it strengthens the adhesiveness between the tile and the substrate and prevents the tile from hollowing, slipping, and cracking.
Improve water retention and prolong open time
