PVA 2688 vs Other PVA Grades
Polyvinyl Alcohol 2688 offers superior performance when compared to other PVA grades such as PVA 2488 and PVA 1788. Here’s how it stands out:
| Grade | Polymerization | Viscosity (mPa·s) | Key Properties | Typical Uses |
|---|---|---|---|---|
| 1788 | 1700 | 20–26 | Fastest dissolve, low viscosity, flexible film, good adhesion | General adhesives, textile sizing, putty, paper coating |
| 2488 | 2400 | 45–55 | Slower dissolve, higher viscosity, stronger film & bond | Mortar, tile adhesive, heavy-duty sizing, thickener |
| 2688 | 2600 | 56–65 | Slowest dissolve, highest viscosity, strongest film & water resistance | High-strength adhesives, construction binders, high-viscosity formulations |
- PVA 1788: Lowest DP, fastest dissolve, flexible, general-purpose
- PVA 2488: Mid DP, medium-high viscosity, balanced strength
- PVA 2688: Highest DP, highest viscosity, strongest film & bond
How to Choose the Right PVA Grade for Your Application
Choosing the right PVA grade depends on the specific application, such as viscosity, film strength, and solubility. For textile sizing, higher viscosity grades like PVA 2688 are preferred, while for adhesives and coatings, PVA 2688 offers excellent flexibility and water resistance.
