Virantage (PESU : Polyethersulfone)
Virantage® polyethersulfone (PESU) tougheners are amorphous, high-temperature thermoplastics used to improve the toughness of thermoset matrix systems while retaining high modulus, high temperature capability, hot-wet performance and resistance to aggressive environments. Functionalized (r-PESU) and non-functionalized powders are available in a range of particle sizes.
