OH Number app for iPhone and iPad

Polyether polyols are broadly used in many polyurethane applications like rigid and elastic foam manufacturing and other advanced plastic materials:

Polyether polyols are described by three main parameters:
Functionality (f)
Molecular weight (Mn)
Hydroxyl number (OH#)

Once you know 2 of those 3 parameters you can calculate the 3rd. "OH Number" app helps to easily do this conversion.

Adjust two parameters with a slider or use buttons for precise control and see immediately the third parameter converted. "OH Number" provides a representation of the chemical formula based on the three parameters.

Change calculation sequence by simple dragging a parameter.


Very simple and productive.
