MDI ester-based systems: Good dynamics and strong resistance to internal heat buildup 

Polywin feature MDI ester-based products in our range, which includes both conventional MDI-based systems as well as three-components MDI prepolymers. S165* ester-based prepolymers are usually processed with alcohol-based curatives and the resulting elastomer generally show very good resistance to abrasion and tears as well as to hydrocarbons, oils, and solvents. They are suitable for applications that require excellent resistance to internal heat buildup and strong dynamic properties. Madsionol® MDI ester systems are used in scrapers, couplings, doffers, squeegees, screens, and many other demanding applications.

Key properties of our MDI ester-based systems:

• Excellent abrasion and tear resistance
