A unique MDI-based technology
Desmodur® amine cross-linked MDI prepolymers for hot cast polyurethane
MDI terminated prepolymers with amine cross-linkers bring together the performance of MDI-based systems with easy processing and good flow-ability.
MDI-terminated prepolymers are used to mold high-performance cast polyurethane elastomers with a wide range of properties, but also demand accurate processing.On the other hand, the processing of TDI-based systems is more permissive but requires more careful handling.
To solve these challenges, Desmodur® MAX systems provide an innovative low-melting two-component amine cross-linked MDI-based solution.
Available in both ether and ester series and crosslinked with amines, the resulting polyurethane elastomers possess superior mechanical properties:
- High elongation
- High resilience
- Excellent tear and tear-propagation resistance
- Exceptional abrasion resistance and hydrolytic stability
- Low compression set values
In addition, long pot-lives and short demolding times with Desmodur® Max systems make these prepolymers suitable for the molding of very large components.
Covestro offers Desmodur® Max prepolymers with a wide range of cross-linking amines, including commonly used MOCA (2,2' dichloro-4,4'-methylene dianiline) and other alternatives.
