The Holtac™ portfolio contains a range of different polyols with varying melting points and hydroxyl numbers. This allows customization of the polyol for your specific PVC processing need. It is also possible to mix several Holtac™ products to achieve a unique performance.

Holtac™ M
Holtac™ M is particularly valued for the early color, long color retention and good maximum heat stability it lends to PVC formulations. 
- Melting point at 262 °C
- Good dynamic heat stability
- Low water absorption

Holtac™ D
Holtac™ D offers the highest performance in lead-free heat stabilizers. It provides outstanding heat stability over long periods and the moderate melting point improves the compatibility of the polyol with the PVC formulation. 
- Melting point at 222 °C
- Excellent dynamic heat stability
- Low water absorption
- Low risk for plate-out
