설명

애플리케이션

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.

특징 및 장점

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.

물리적 형태

Thermoplastic elastomer.
