Organometal-free polyurethane with low leach |
| abstract |
The present invention relates to a moisture-permeable thermoplastic polyurethane prepared from the reaction of a polyol component, a polyisocyanate component and a chain extender in the presence of a metal free catalyst. Metal free catalysts include polyalcohol amines, tertiary amine catalysts, or mixtures thereof. The polyurethanes of the present invention are suitable for film products because they form a moisture-permeable film that is not permeable to air or water but is permeable to water vapor. The polyurethane composition is substantially free of metals, contains less leach, and has excellent melt strength. |
