For the extrusion of polyurethane foils we deliver a broadly based assortment of basic raw materials.
Chrystallinisation polyurethane granules are unique basic materials for thermo-, hot seal- and other high-performance hot melt foils. You will find non- and partly crystallisation TPU's which will be applied to produce compact PUR-foils.
Aromatic structured TPU's will be used to produce polyurethane foils, which will provide good mechanical characteristics, high wear and tear characteristic, excellent low-temperature impact strength and sufficient resistance to oil, grease and chemicals.
The disadvantage of these aromatic TPU-systems, which contain mainly MDI (methylene diisocyante) as isocyanate component, is that they will have a yellow tendency by the influence of light. UV-stabilizers can prolong this tendency but can't eliminate it. For applications, by which this tendency must be avoided and a light stability is in any case required, aliphatic based TPU's must be applied.
The TPU elastomers and DANTHANE compounds offered by Danquinsa GmbH are suitable for the production of film applications by the following methods:
- Flat film extrusion
- Blow film extrusion
- Mono- and co extrusion of films / foils
If you produce PUR-films, you should not neglect to get to know our thermoplastic TPU's / PUR-elastomers for your PUR-films.
