Beschreibung

Anwendung

Component of hot melt adhesives, sealants, asphalt and oil gels. Modifier for polymers, thermosets and general rubber compounding. Direct molded or extruded auto parts, sporting goods, footware and film.

Leistungsmerkmale und Vorteile

Maleic anhydride is grafted on the mid-block to increase compatibility with polar coatings and increase interaction with substrates. More oxidatively stable than unsaturated precursor. Flexible to -80°C.

Physikalische Form

Thermoplastic elastomer.
