Polyethersulfone
Veradel? PESU was formerly marketed as Gafone? PESU
Veradel 3000P, 3100P, 3200P, 3400P, and 3600P are
polyethersulfone (PESU) powders for dissolving or dispersing
into solutions. They can also be ground to smaller
particle size, or blended with other solid particles.
PESU offers excellent toughness and outstanding hydrolytic
resistance. It resists attack from steam, boiling
water, and mineral acids. Cast films or coatings of PESU
are transparent and have additional desirable properties
including long term thermal stability, excellent metal
adhesion and formability, and inherent flame resistance.
A range of molecular weights are available, from 3000P
which is the highest to 3600P, the lowest. There is a
direct correlation between molecular weight and solution
viscosity.
Typical applications include high-temperature coating
formulations, membranes, advanced high-temperature
composites, and specialty adhesives.
