Applications

Transportation

Thermoset epoxies offer strength, stiffness, chemical resistance, high glass transition temperature, and hot-wet performance. However, these desirable properties are often achieved at the expense of toughness, which can lead to low damage tolerance in carbon fiber reinforced epoxy composites. 

High-temperature thermoplastics such as Virantage® polyethersulfone (PESU) improve the toughness of epoxy systems while retaining high modulus, high temperature capability, hot-wet performance and resistance to aggressive environments.

Typical application areas include aerospace, military aircraft, automotive. 

Industrial

Virantage® polyethersulfone (PESU) can also be used to improve the toughness of thermoset matrix systems used for industrial applications such as wind power generation. Functionalized PESU can also be used for high-temperature coating formulations and specialty adhesives due to outstanding hydrolytic resistance, long term thermal stability, excellent metal adhesion and formability and inherent flame resistance.
